    Answer: (c) 35° (d) 65°

    Step-by-step explanation:

    Let x represent one of the angles.

    Then the other angle is represented by 2x - 15.

    Complementary means their sum is 90°

    Supplementary means their sum is 180°

    a) x + (2x - 15) = 90°

    3x - 15 = 90°

    3x = 105°

    x = 35°

    b) x + (2x - 15) = 180°

    3x - 15 = 180°

    3x = 195°

    x = 65°
