    In the given figure, \[\angle PAD={{30}^{o}}\] is inscribed in a circle with centre O. If the length of the chord YZ is equal to the radius of the circle, then \[\angle CPA={{45}^{o}}\] =____

    A)  \[\angle CBP\]                        

    B)  \[{{105}^{o}}\]

    C)  \[{{115}^{o}}\]                              

    D)  \[{{135}^{o}}\]

    Correct Answer: B

    Solution :

    \[{{360}^{o}}\] \[{{360}^{o}}\] So \[AB||DC\]is an equilateral triangle. \[AB||DC,AD||BC\] \[AB=CD,AD=BC\] Now, \[OA=OC,OB=OD\]
