Answer 1

(c)

we know that:-

sum of all angle of quad. = 360°

<A + <B + <C + <D = 360°

90 + (5a + 10°) + (3a + 15°)+ (2a+ 5°). =360

10a + 120 = 360

10 a. = 240

a. = 24

A=90°

B=5a+ 10 =130 °

C=3a+15 = 87°

D=2a+ 5.= 53°

let me check

sum of all angle of quad. = 360

<A + <B + <C +<D

90+ 130 + 87 + 53 = 360....
