Question

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

Answer 1

☆ Solution ☆

Given :-

• One of the exterior angles of triangle is 100° .

• The interior opposite angle are equal to each other.

To Find :-

• The measure of these of equal interior opposite angles.

Step-by-Step-Explaination :-

As we know that :-

Sum of 2 opposite interior angles is equal to exterior angle.

So, let one interior angle = x

and other interior angle = x

So,

x + x = 100

2x = 100

x = 100/2

x = 50°

Hence,

Each interior angle = 50°
