Question : In $\triangle A B C $, AB and AC are produced to points D and E, respectively. If the bisectors of $\angle C B D$ and $\angle B C E$ meet at the point O, and $\angle B O C=57^{\circ}$, then $\angle A$ is equal to:
Option 1: 93°
Option 2: 66°
Option 3: 114°
Option 4: 57°
Correct Answer: 66°
Solution : Given: $\angle BOC = 57^\circ$ ⇒ $\angle BOC = 90^\circ – \frac{\angle BAC}{2}$ ⇒ $\frac{\angle BAC}{2} = 90^\circ – 57^\circ$ ⇒ $\frac{\angle BAC}{2} = 33^\circ$ ⇒ $\angle BAC = 66^\circ$ Hence, the correct answer is $66^\circ$.
