    In the given figure, \[\angle CBP\] is inscribed in a circle. The bisector of \[{{105}^{o}}\] meets BC at D and the circle at E. If EC is joined then\[{{115}^{o}}\]. Find \[{{135}^{o}}\].

    A)  \[\Delta ABC\]                        

    B)  \[\angle BAC\]

    C)  \[\angle ECD={{30}^{o}}\]                       

    D)  \[\angle BAC\]

    Correct Answer: D

    Solution :

    \[OM\bot AB\] Angle in same segment are equal \[\angle A\] \[\angle D\]  AD is a bisector, So  \[\angle AOD\] \[{{45}^{o}}\]  \[{{90}^{o}}\]
