If in a triangle ABC as drawn in the figure, AB = AC and ∠ ACD = 120°, then ∠ A is equal to A

1. 50°
2. 60°
3. 70°
4. 80°

Correct Option: B

On the basis of given question , we draw a figure of triangle ABC

Given , AB = AC and ∠ ACD = 120°
∠ ACB = 180° - ∠ ACD = 180° – 120° = 60°
∴ ∠ ABC = ∠ ACB = 60°
∴ ∠ BAC = 60°
