    Answer:

    mAngleB= 50

    mAngleC= 130

    Explanation:

    Complementary angles = 90

    So If angle A is 40 subtract that to 90 to find angle B which is 50

    and 50+40= 90 = Complementary

    Supplementary angles = 180

    So if angle C is supplementary to angle B you would need to subtract 50 from 180 to find angle C which is 130

    130+20= 180 = supplementary
