    In a cyclic quadrilateral ABCD, angle A = 70 degrees and angle B = 100 degrees. What is the measure of angle C?

    A 120 degrees Correct Answer Incorrect Answer
    B 110 degrees Correct Answer Incorrect Answer
    C 85 degrees Correct Answer Incorrect Answer
    D 65 degrees Correct Answer Incorrect Answer

    Solution

    ATQ, In a cyclic quadrilateral, opposite angles are supplementary. So, angle C = 180 - angle A = 180 - 70 = 110 degrees.
