    In the given circle, 0 is the centre and\[{{50}^{o}}\]. Then \[{{55}^{o}}\] is equal to

    A)  \[{{108}^{o}},{{72}^{o}}\]                               

    B)  \[{{72}^{o}},{{36}^{o}}\]

    C)  \[{{100}^{o}},{{80}^{o}}\]                   

    D)  \[{{144}^{o}},{{36}^{o}}\]

    Correct Answer: C

    Solution :

    \[{{60}^{o}}\](Angles in the same segment) \[\angle BAC={{45}^{o}}\](Angle in a semi-circle) \[\angle BED={{120}^{o}}\] \[\angle ABD\]
