    In the given figure; O is the centre of the circle and \[\angle BDC={{42}^{o}}.\]The measure of\[\angle BAC\]is _____.

    A)  \[{{42}^{\text{o}}}\]                                     

    B)        \[{{48}^{o}}\]

    C)        \[{{58}^{o}}\]

    D)        \[{{52}^{o}}\]

    Correct Answer: A

    Solution :

    Given, \[\angle BDC={{42}^{o}}\] Since, angles in same segment are equal. \[\therefore \]\[\angle BAC=\angle BDC={{42}^{o}}\]
