    In figure points A, B, C and D are co cyclic and \[ED||AC\], then \[DA\bot AB,\]is equal to:

    A)  \[CB\bot AB\]                        

    B)  \[OM\bot AB\]              

    C)  \[\angle A\]                             

    D)  \[\angle D\]          

    Correct Answer: B

    Solution :

    Given:  \[\angle BOD={{120}^{o}}\] \[\angle ACD\] \[{{30}^{o}}\]                      (Linear pair) Now, ADCB is a quadrilateral and sum of opposite angle \[{{40}^{o}}\] \[{{60}^{o}}\] \[{{90}^{o}}\] Now,  \[{{30}^{o}}\]    (Linear pair)
