A) \[{{90}^{o}}-\frac{A}{2},{{90}^{o}}-\frac{B}{2},{{90}^{o}}-\frac{C}{2}\]
B) \[{{90}^{o}},{{60}^{o}},{{30}^{o}}\]
C) \[\frac{A}{2},\frac{B}{2},\frac{C}{2}\]
D) \[\frac{B}{2},\frac{A}{2},\frac{A}{2}-\frac{B}{2}\]
Correct Answer: A
Solution :
Clearly, \[\angle BYX=\angle BAX=\frac{\angle A}{2}.\] Also \[\angle ZYB=\angle ZCB=\frac{\angle C}{2}.\](Angles in the same segment.)You need to login to perform this action.
