    In the figure below, if \[\angle \text{ABC}\] is a right angle then \[\angle \text{ABD}\] is equal to:

    A) \[49{}^\circ \]                   

    B)        \[41{}^\circ \]

    C) \[51{}^\circ \]                    

    D)        \[59{}^\circ \]

    E) None of these

    Correct Answer: B

    Solution :

    Explanation: Option (b) is correct. Here, \[\angle \text{ABD}+\angle \text{CBD}=90{}^\circ \]and \[\angle \text{CBD}=49{}^\circ \] Therefore, \[\angle \text{ABD}=90{}^\circ -49{}^\circ =41{}^\circ \]
