Question

Answer the following

Answer 1

Explanation:

61)4 + 5(p-1) = 34 {Distributive property}

4 + 5p - 5 = 34 {Add like terms}

5p - 1 = 34 {Add 1 to both sides}

5p = 34+1

5p = 35 {Divide both sides by 5)

p = 35/5

p = 5

62) Smaller angle = x

Larger angle = x +50

x + (x +50) = 180 {Supplementary angles}

2x + 50 = 180 {Subtract 50 from both sides}

2x = 180 -50

2x = 130

x = 130/2

x = 65

Smaller angle = 65

Larger angle = 65 + 50 = 115

63) ΔBAD , ΔBCD

BA ≅ BC

∠A ≅ ∠C

AD ≅ CD

ΔBAD ≅ΔBCD {S A S congruent}

64) Selling price = ₹ 5500

Profit = 10%

`Cost price = (100)/(100+profit)*SP\\\\= (100)/(100+10)*5500\\\\=(100)/(110)*5500\\\\=100*50\\\\=5000=`
