    Among the angles\[{{30}^{o}},\,\,{{36}^{o}},\,\,{{45}^{o}},\,\,{{50}^{o}}\]one angle cannot be an exterior angle of a regular polygon. The angle is

    A) \[{{30}^{o}}\]                        

    B) \[{{36}^{o}}\]

    C) \[{{45}^{o}}\]            

    D)        \[{{50}^{o}}\]  

    Correct Answer: D

    Solution :

     Sum of exterior angles of a regular polygon\[={{360}^{o}}\] But \[\frac{{{360}^{o}}}{50}=7.2\ne \]a whole number.
