    B 10 Correct Answer Incorrect Answer
    C 12 Correct Answer Incorrect Answer
    D 15 Correct Answer Incorrect Answer

    Solution

    The formula for the interior angle of a regular polygon with n sides is: Interior angle = [(n - 2) * 180] / n. 144 = [(n - 2) * 180] / n. 144n = 180n - 360 36n = 360 n = 10.
