Question

An exterior angle of a triangle measures 105 degrees. Explain how to find the measure of the adjacent interior angle of the triangle.

Answer 1

Step-by-step explanation:

Given exterior angle of triangle= 105°

Let the two opposite interior angles of triangle = x

We know that

Exterior angle of a triangle = sum of interior opposite angles

Therefore

105° = x + x

2x = 105°

X = 52.5°
