Question

Solve Ques. no. 8.

Its urgent........

Answer 1

Answer:

Step-by-step explanation:

Since it is a cyclic quadrilateral, the sum of opposite angles = 180°

⇒ 3 y - 5 - 7 x + 5 = 180

⇒3 y - 7 x = 180 .............. i

⇒4 y + 20 - 4 x = 180

⇒ 4 y - 4 x = 160

⇒ y - x = 40 ............ ii

By solving i and ii

We get x = -15 y = 25

By adding values,

<A = 120°

<B = 80°

<C = 60°

<D = 120°
