    The angles of a pentagon in degree are \[{{70}^{o}}\]\[{{115}^{o}}\]and \[\Delta ABC\]. What is the measure of the largest angle?

    A)  \[DG||EF\]                           

    B)  \[\Delta ABC\]

    C)  \[DE||BC\]                           

    D)  \[EF||AD\]

    Correct Answer: B

    Solution :

    As we know, sum of angles of pentagon = \[{{136}^{o}}\] \[{{180}^{o}}\] \[{{68}^{o}}\]\[\angle BCD=.......\] \[{{60}^{o}}\]  \[{{120}^{o}}\] \[{{72}^{o}}\] Largest angle \[{{180}^{o}}\]
