    In the given figure, \[\angle PAQ\]is equal to

    A) \[{{45}^{o}}\]

    B) \[{{100}^{o}}\]

    C) \[{{35}^{o}}\]

    D)         None of these   

    Correct Answer: B

    Solution :

    \[9x+20x+7x={{180}^{o}}\] \[\Rightarrow \]\[36x={{180}^{o}}\Rightarrow x={{5}^{o}}\] \[\therefore \]\[\angle PAQ=20(5)={{100}^{o}}\]
