Solution:
i. Let the measure of the complementary
angle be x°.
35 + x = 90
∴35 + x-35 = 90 – 35
….(Subtracting 35 from both sides)
∴x = 55
∴The complementary angle of 35° is 55°.

ii. Let the measure of the complementary angle be x°.
a + x = 90
∴a + x – a = 90 – a
….(Subtracting a from both sides)
∴x = (90 – a)
∴The complementary angle of a° is (90 – a)°.

iii. Let the measure of the complementary angle be x°.
22 + x = 90
∴22 + x – 22 = 90 – 22
….(Subtracting 22 from both sides)
∴x = 68
∴The complementary angle of 22° is 68°.

iv. Let the measure of the complementary angle be a°.
40 – x + a = 90
∴40 – x + a – 40 + x = 90 – 40 + x
….(Subtracting 40 and adding x on both sides)
∴a = (50 + x)
∴The complementary angle of (40 – x)° is (50 + x)°.

Question 14.
Find the measures of the supplements of the following angles:
i. 111°
ii. 47°
iii. 180°
iv. (90 – x)°
Solution:
i. Let the measure of the supplementary
angle be x°.
111 + x = 180
∴ 111 + x – 111 = 180 – 111
…..(Subtracting 111 from both sides)
∴ x = 69
∴ The supplementary angle of 111° is 69°.

ii. Let the measure of the supplementary angle be x°.
47 + x = 180
∴47 + x – 47 = 180 – 47
….(Subtracting 47 from both sides)
∴x = 133
∴The supplementary angle of 47° is 133°.

iii. Let the measure of the supplementary angle be x°.
180 + x = 180
∴180 + x – 180 = 180 – 180
….(Subtracting 180 from both sides)
∴x = 0
∴The supplementary angle of 180° is 0°.

iv. Let the measure of the supplementary angle be a°.
90 – x + a = 180
∴90 – x + a – 90 + x = 180 – 90+ x
….(Subtracting 90 and adding x on both sides)

1. m∠PRT
2. m∠P
3. m∠Q

Solution:
Here, ∠PRQ and ∠PRT are angles in a linear pair.
m∠PRQ + m∠PRT = 180°
∴70 + m∠PRT = 180
∴m∠PRT = 180 – 70
∴m∠PRT = 110°
Now, ∠PRT is the exterior angle of ∆PQR.
∴m∠P + m∠Q = m∠PRT
∴m∠P + m∠P = m∠PRT ….(The measures of ∠P and ∠Q is same)

Solution:
Here, P = Rs 15000, R = 9 p.c.p.a., I = Rs 5400

∴ T = 4
∴ Angela had deposited the amount for 4 years.

Question 2.
Ten men take 4 days to complete the task of tarring a road. How many days would 8 men take?
Solution:
Let us suppose that 8 men require x days to tar the road.
Number of days required by 10 men to tar the road = 4
The number of men and the number of days required to tar the road are in inverse proportion.
∴ 8 × x = 10 x 4
∴ \(x=\frac{10 \times 4}{8}\)
∴ x = 5
∴ 8 men will require 5 days to tar the road.

Question 3.
Nasruddin and Mahesh invested Rs 40,000 and Rs 60,000 respectively to start a business. They made a profit of 30%. How much profit did each of them make?
Solution:
Total amount invested = Rs 40,000 + Rs 60,000
= Rs 1,00,000
Profit earned = 30%
∴ Total profit = 30% of 1,00,000
= \(\frac { 30 }{ 100 }\) × 100000
= Rs 30000
Proportion of investment = 40000 : 60000
= 2:3 …. (Dividing by 20000)
Let Nasruddin’s profit be Rs 2x and Mahesh’s profit be Rs 3x.
∴ 2x + 3x = 30000
∴ 5x = 30000
∴ x = \(\frac { 30000 }{ 5 }\).
∴ x = 6000
∴ Nasruddin’s profit = 2x = 2 × 6000 = Rs 12000
Mahesh’s profit = 3x = 3 × 6000 = Rs 18000
∴ The profits of Nasruddin and Mahesh are Rs 12000 and Rs 18000 respectively.

ii. (10 + y)²
iii. \(\left(\frac{p}{3}+\frac{q}{4}\right)^{2}\)
iv. \(\left(y-\frac{3}{y}\right)^{2}\)
Solution:
i. Here, A = 2a and B = 3b
∴ (2a – 3b)² = (2a)² – 2 × 2a × 3b + (3b)²
…. [(A – B)² = A² – 2AB + B²]
= 4a² – 12ab + 9b²

ii. Here, a = 10 and b = y
(10 + y)² = 102 + 2 × 10xy + y²
…. [(a + b)² = a² + 2ab + b²]
= 100 + 20y + y²

iii. Here, a = \(\frac { p }{ 3 }\) and b = \(\frac { q }{ 4 }\)
\(\left(\frac{p}{3}+\frac{q}{4}\right)^{2}=\left(\frac{p}{3}\right)^{2}+2 \times \frac{p}{3} \times \frac{q}{4}+\left(\frac{q}{4}\right)^{2}\)
…. [(a + b)² = a² + 2ab + b²]
\(\frac{p^{2}}{9}+\frac{p q}{6}+\frac{q^{2}}{16}\)

iv. Here, a = y and b = \(\frac { 3 }{ y }\)
\(\left(y-\frac{3}{y}\right)^{2}=y^{2}-2 \times y \times \frac{3}{y}+\left(\frac{3}{y}\right)^{2}\)
…. [(a – b)² = a² – 2ab + b²
= \(y^{2}-6+\frac{9}{y^{2}}\)

Question 6.
Use a formula to multiply:
i. (x – 5)(x + 5)
ii. (2a – 13)(2a + 13)
iii. (4z – 5y)(4z + 5y)
iv. (2t – 5)(2t + 5)
Solution:
i. Here, a = x and b = 5
(x – 5)(x + 5) = (x)² – (5)²
…. [(a + b)(a – b) = a² – b²]
= x² – 25

ii. Here, A = 2a and B = 13
(2a – 13)(2a + 13) = (2a)² – (13)²
…. [(A + B)(A – B) = A² – B²]
= 4a² – 169

iii. Here, a = 4z and b = 5y
(4z – 5y)(4z + 5y) = (4z)² – (5y)²
…. [(a + b)(a – b) = a² – b²]
= 16z² – 25y²

iv. Here, a = 2t and b = 5
(2t – 5)(2t + 5) = (2t)² – (5)²
…. [(a + b)(a – b) = a² – b²]
= 4t² – 25

Question 7.
The diameter of the wheel of a cart is 1.05 m. How much distance will the cart cover in 1000 rotations of the wheel?
Solution:
Diameter of the wheel (d) = 1.05 m
∴ Distance covered in 1 rotation of wheel = Circumference of the wheel
= πd
= \(\frac{22}{7} \times 1.05\)
= 3.3 m
∴ Distance covered in 1000 rotations = 1000 x 3.3 m
= 3300 m
= \(\frac { 3300 }{ 1000 }\) km …[1m = \(\frac { 1 }{ 1000 }\)km]
= 3.3 km
∴ The distance covered by the cart in 1000 rotations of the wheel is 3.3 km.

Question 8.
The area of a rectangular garden of length 40 m, is 1000 sq m. Find the breadth of the garden and its perimeter. The garden is to be enclosed by 3 rounds of fencing, leaving an entrance of 4 m. Find the cost of fencing the garden at a rate of Rs 250 per metre.
Solution:
Length of the rectangular garden = 40 m
Area of the rectangular garden = 1000 sq. m.
∴ length × breadth = 1000
∴ 40 × breadth = 1000
∴ breadth = \(\frac { 1000 }{ 40 }\)
= 25 m
Now, perimeter of the rectangular garden = 2 × (length + breadth)
= 2 (40 + 25)
= 2 × 65
= 130 m
Length of one round of fence = circumference of garden – width of the entrance
= 130 – 4
= 126 m
∴ Total length of fencing = length of one round of wire × number of rounds = 126 × 3
= 378 m
∴ Total cost of fencing = Total length of fencing × cost per metre of fencing
= 378 × 250
= 94500
∴ The cost of fencing the garden is Rs 94500.

Question 9.
From the given figure, find the length of hypotenuse AC and the perimeter of ∆ABC.
Solution:

In ∆ABC, ∠B = 90°, and l(BC) = 21, and l(AB) = 20
∴ According to Pythagoras’ theorem,
∴ l(AC)² = l(BC)² + l(AB)²
∴ l(AC)² = 21² + 20²
∴ l(AC)² = 441 + 400
∴ l(AC)² = 841
∴ l(AC)² = 29²
∴ l(AC) = 29
Perimeter of ∆ABC = l(AB) + l(BC) + l(AC)
= 20 + 21 + 29
= 70
∴ The length of hypotenuse AC is 29 units, and the perimeter of ∆ABC is 70 units.

Question 10.

‘माळढोक पक्ष्याला शेतकऱ्याचा मित्र असे का म्हटले आहे?
उत्तर:
माळढोक पक्ष्याला शेतकऱ्याचा मित्र असे म्हटले आहे, कारण शेतातील किड्यांवर तो गुजराण करतो. त्यामुळे शेतातील किडे कमी होऊन पिकांचे त्यांपासून रक्षण होते.

माळढोक पक्षी वर्षातून एकदाच अंडी घालतो. शिवाय त्यांची अंडी जमिनीवर असल्याने इतर प्राणी ती तुडवून जातात, त्यामुळे माळढोक पक्ष्यांची संख्या कमी होत आहे.

कृती 4 : स्वमत

प्रश्न 1.
पक्षी हा संतुलित पर्यावरणाचा अविभाज्य घटक आहे, याविषयी तुमचे मत लिहा.
उत्तर:
निसर्ग हा सजीव व निर्जीव घटकांनी बनला आहे. यातील ङ्केप्रत्येक पटकांचा आकार, रंग, गुण हे वैशिष्टयपूर्ण असतात. पक्षीसुद्धा निसर्गाच्या या अविभाज्य घटकांपैकीच एक आहेत. निसर्गाच्या अन्नसाखळीत ते कुणाचे तरी भक्ष्य बनत असतात तर कुणाचे तरी ते भक्षक बनत असतात. अन्नसाखळीतील त्यांच्या या भूमिकेमुळे पर्यावरणाचा समतोल साधला जातो.

प्रश्न 2.
पक्ष्यांची संख्या वाढण्यासाठी तुम्ही काय करू शकता, याबद्दलची तुमची भूमिका स्पष्ट करा.
उत्तर:
आजकाल निसर्गातील अनपेक्षित व अनिष्ट बदलांचा परिणाम प्राणीजीवनाबरोबरच पक्ष्यांवरही होताना दिसतो. दिवसेंदिवस वाढणारी उष्णता व त्याच वेगाने निर्माण होणारी पाण्याची कमतरता यांमुळे पक्षांचे जीवन संकटात सापडले आहे. त्यांच्या वेगवेगळ्या प्रजातींची संख्या वाढवण्यासाठी शासकीय पातळीवर पक्षी अभयारण्ये उभारण्यासाठी जनजागृती मोहीम हाती घेऊ, तसेच मनुष्यवस्ती असलेल्या भागांत त्यांच्या दाणापाण्याची व्यवस्था करू.

त्याचबरोबर पक्ष्यांचे जीवन सुसहर होण्यासाठी वृक्षलागवडीसारखे उपक्रम हाती घेऊ. एवढेच नाही तर ज्या प्रजाती नष्ट होण्याच्या मार्गावर आहेत अशा प्रजातींचे रक्षण करण्यासाठी शासकीय स्तरावर त्यांच्या शिकारीस व हत्येस प्रतिबंध करू.

• आई : पक्षी आपण टाकून दिलेल्या फळांच्या बिया खातात, व त्यांच्या विष्ठेतून त्या बाहेर पडतात. त्यातूनच काही बिया रूजतात व झाडे उगवतात.

• आई : होय! जंगलात झाडे लावायला आपण जातो का?
• राधिका : नाही?
• आई : ती सर्व झाडे पक्ष्यांमुळेच उगवतात. आपल्या आजूबाजूला जी बडा-पिंपळाची झाडे दिसतात ना, ती ही तशाच प्रकारे उगवली आहेत.
• राधिका : आई, तू म्हणतेस ते अगदी बरोबर आहे. अजून पक्षी कोणते काम करतात?

राज : नाही
सुवर्णा : थांब मी तुला सांगते. आपल्या सर्व मित्र मैत्रिणींना पण तू बोलव! (सर्व मित्र मैत्रिणी एकत्र येतात.) आपल्याला सर्वांना पक्ष्यांची संख्या वाढविण्यासाठी काय करता येईल. यावर चर्चा करावयाची आहे. तर मग सांगा पाहू. (एकेक जण सांगू लागतात.)

दि.10 जुन 2018

प्रिय मित्र सुनिल यास,
सप्रेम नमस्कार तुझे पत्र मिळाले. यावेळी मे महिन्यात आई बाबांबरोबर मी महाबळेश्वरला गेलो होतो. त्यामुळे तुला पत्र लिहू शकलो नाही.

महाबळेश्वर हे उत्तम पर्यटन स्थळ आहे. अरे तिथले वातावरण तर खूपच सुंदर आहे. आम्ही तिचे सनसेट पॉईंटला गेलो होतो. तिथे इतका जोराचा वारा येतो की मला क्षणभर वाटले की मी ही वाऱ्याबरोबर उडून जातो की काय?

तसेच तेथे घोड्यावर रपेटही मारली. बोटींग केले. शेतातून काढलेली ताजी टवटवीत स्ट्रॉबेरीही आम्हांला खायला मिळाली.

तेथील बाजारात किती तरी हस्तकौशल्याच्या वस्तूही बघायला मिळाल्या. तेथील निसर्गरम्य वातावरणातून परत येण्याची इच्छाच होत नव्हती; पण काय करणार यावेच लागले. माझा अभ्यास व्यवस्थित सुरू आहे. तुझी खुशाली वरचेवर कळव.

तूबै एकदा महाबळेश्वरला जाऊन ये. तुझ्या आई बाबांना माझा शि. सा. नमस्कार. बाकी सर्व ठीक आहे.

तुझा मित्र.
