    Angle bisectors of Q and R meet at point S, inside the

    triangle PQR. If angle QSR = 128˚ , then the measure of angle P is:
    A 76˚ Correct Answer Incorrect Answer
    B 50˚ Correct Answer Incorrect Answer
    C 80˚ Correct Answer Incorrect Answer
    D 68˚ Correct Answer Incorrect Answer

    Solution

    So, angle QSR = 90 + (angle P)/2 => 128 = 90 + (angle P)/2 => angle P = 38 x 2 = 76˚
