Question

if ABCD is cyclic quadrilateral if angle A and angle C are in the ratio 2:3 ,then we have : angle A and angle C as
​

Answer 1

Answer:

Let /_A = 2x and /_C = 3x.

We know, sum of opposite angles of a cyclic quadrilateral = 180°

So, /_A + /_C = 180°

2x + 3x = 180

5x = 180

x = 36

So /_ A = 72°

and /_C = 108°
