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?
Explanation:
Let the measure of other two angle be x° each.
∴ Sum of the three angles of a triangle is 180° = 108° + x + x
⇒ 2x = 180° - 108° = 72°
⇒ x = 36°
Hence, option (a).
