Question

in a cyclic [] abcd , twice the measure of angle A is eqal to thrice the measure of angle C find the measure of angle C A) 36° B) 72° C) 90° D)108°​

Answer 1

Answer:

D) 108°

Step-by-step explanation:

We know that , sum of two opposite angles of a quadrilateral is 180° .

2 angle A + 3 angle C = 180°

5 angle = 180°

Angle = 180°

5

Angle = 36°

Angle A = 2 × 36°

= 72°

Angle C = 3 × 36°

= 108°
