    Find the each interior angle of Pentagon?

    A) \[120{}^\circ \]            

    B) \[130{}^\circ \]

    C) \[108{}^\circ \]

    D) \[102{}^\circ \]

    Correct Answer: C

    Solution :

    In Pentagon, side n = 5 Now, each interior angle of Polygon \[=\frac{(n-2)\times 180}{n}\] So, each interior angle of Pentagon \[=\frac{(5-2)\times 180}{5}\] \[=\frac{3\times 36\times 5}{5}\] \[=3\times 36\] \[=108{}^\circ \]
