Question

One of the exterior angles of a triangle is 100 and it's interior opposite angles are equal to each other . What is the measure of each of these two angles

Answer 1

let the two equal opposite angles be x

By exterior angle property

x + x= 100

2x = 100

x = 50

Thus the each angle is 50°

Answer 2

Step-by-step explanation:

Since we know that sum of 2 opposite interior angles is equal to exterior angle.

So, let one int. angle=x

& other int. angle=x

So, x+x= 100

2x=100

x=100/2

x=50

Therefore, each interior angle = 50°
