Question
Find the unknown angles in the given figure:
✓
Answer
In the figure, m = 35° .........(Angles opposite to equal sides) But m + n + (60° + 35°) = 180° ..........(Angles of a triangle) ⇒ m + n + 95° = 180° ⇒ 35° + n + 95° = 180° ⇒ n + 130° = 180° ⇒ n = 180° − 130° = 50° Hence m = 35°, n = 50°
