Question

4. One of the exterior angles of triangle is 100°. The interior opposite angles are equal to
each other. Find the measure of these equal interior opposite angles​

Answer 1

Answer:

let Triangle ABC are the traingle where Angle A =angle B

and angle ACD are the exterior angle outside the Circle

According to exterior angle theorem

Angle A + Angle B =Angle ACD

2(Angle A)=100°

Angle A =50°

therefore Angle A=Angle B= 50°
