One of the angles of a triangle is 108°, and the other two angles are equal. What is the measure of each of these equal angles?

36° 72° 78° 39°

36°

Let us consider three angles of a triangle ABC = ∠A , ∠B & ∠C Let us consider ∠A = 108º  & ∠B = ∠C So, 108º  + ∠B + ∠C = 180º 2∠B = 72º ∠B = 36º  SO, One of these angles is 36º
