In $\triangle ABC, \angle A = 66^\circ$. AB and AC are produced to points D and E, respectively. If the bisectors of angle CBD and angle BCE meet at the point O, then $\angle BOC$ is equal to:
Answer & explanation
Correct answer: option 3
\(\angle\)BOC = 90 - \(\angle\)A/2
= \(\angle\)BOC = 90 - \(\frac{66}{2}\)
= \(\angle\)BOC = 90 - 33
= \(\angle\)BOC = \({57}^\circ\)
Therefore, \(\angle\)BOC is \({57}^\circ\).
