    In the following figure, if O is the centre of the circle, then find x.

    A)  \[{{120}^{o}}\]                              

    B)  \[{{115}^{o}}\]

    C)  \[{{95}^{o}}\]                   

    D) None of these

    Correct Answer: C

    Solution :

    In the given figure \[BD=CD\]is an angle at the center \[\Rightarrow \] is an angle at the remaining part of circle. So, \[\frac{AO}{OD}=\frac{2}{1}\] \[AO:OD=2:1\] \[\angle A,\angle B,\angle C\] \[\angle D\]
