    In the given figure, measure of \[\angle ABC\]is

    A)  \[20{}^\circ \]             

    B)  \[40{}^\circ \]

    C)  \[60{}^\circ \] 

    D)  \[80{}^\circ \]

    Correct Answer: C

    Solution :

    \[\angle ADC+\angle EDC=180{}^\circ \] \[\Rightarrow \]\[\angle ADC+120{}^\circ =180{}^\circ \] \[\Rightarrow \]   \[\angle ADC=60{}^\circ \] \[\angle ABC=\angle ADC=60{}^\circ \] (\[\because \]angles in the same segment).
