    In the given figure, two chords AB and CD of a circle intersect each other at a point E such that\[{{75}^{o}}\],\[{{105}^{o}}\]. Then find\[{{85}^{o}}\].

    A)  \[{{60}^{o}}\]              

    B)  \[\angle BAC={{45}^{o}}\]

    C)  \[\angle BED={{120}^{o}}\]                                 

    D)  \[\angle ABD\]                    

    Correct Answer: A

    Solution :

    Angles in the same segment are equal. \[{{55}^{o}}\]   \[{{70}^{o}}\] In \[\Delta BED,\] \[l||m,\] \[{{130}^{o}}\] \[{{50}^{o}}\] \[\therefore \]\[{{120}^{o}}\]
