    Nothing to verify because you did not say what they are.

    You want to know them?

    Complement angle of 20 deg is 70 deg. ---answer.
    Complementary angles are 90 degrees.

    Supplement angle of 3pi/5 is
    2pi -3pi/5 = (10pi -3pi)/5 = 7pi/5 ---answer.
    Supplementary angles are 2pi radians.
