Question

Two angles in a triangle are equal and their sum is equal to the third angle in the triangle. What are the measures of each of the three interior angles?

The triangle has angles of ,, and  degrees.

Answer 1

2A = T

2A +T = 180

T+T = 180

2T = 180

T = 180/2 = 90

2A = 90

A = 90/2 = 45

angles are 45, 45 and 90 degrees
