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?

Answer 1

45º, 45º, 90º

Explanation:

Assume angles are x then third is x+x = 2x.

sum of angles in a triangle = 180

=> x + x + 2x = 180

=> 4x = 180

=> x = 180/4 = 45

so, angles are 45,45 and 90.
