Answer 2

Answer: UR REQUIRED ANSWER ;-

the rate of angle A : angle D = 5 : 7

Let , the angle A = 5x

and the angle D = 7x

Let , angle A + angle D = 180° ( sum of adjacent angle of trapezium )

5x + 7x = 180°

12 x = 180 °

x = 15°

so ,

angle A : 5 x ⇒ 5 × 15 = 75°

angle D : 7x ⇒ 7 × 15 = 105 °
