    If one angle of a triangle is greater than other two angles by \[30{}^\circ ,\] then the angles of the triangle are:

    A)  \[40{}^\circ ,\,\,40{}^\circ ,\,\,100{}^\circ \]       

    B)  \[50{}^\circ ,\,\,50{}^\circ ,\,\,80{}^\circ \]

    C)  \[30{}^\circ ,\,\,30{}^\circ ,\,\,120{}^\circ \]       

    D)  \[35{}^\circ ,\,\,35{}^\circ ,\,\,110{}^\circ \]

    Correct Answer: B

    Solution :

         \[50{}^\circ +30{}^\circ =80{}^\circ ,\,\,50{}^\circ +30{}^\circ =80{}^\circ \]
