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?
Answer & explanation
Correct answer: option 1
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
