    Triangle has a 180 degrees.

    180-45=135 degrees

    The total of the other degrees are 4b.

    135 divided by 4 = 33.75 degrees = b

    B = 33.75 X 1 = 33.75 degrees

    C = 33.75 X 3 = 101.25 degrees

    Check:

    A = 45

    B = 33.75

    C = 101.25

    Triangle ABC = 180 degrees

    Since there are only three angels I guess this is a triangle

    180 = 45 + b + 3b

    180 = 45 + 4b

    180-45 = 45 - 45 + 4b

    135 = 4b

    135/4 = 4b/4

    b = 33.75

    angle b = 33.75

    angle c = 101.25

    Check

    40 + 33.75 + 101.25 = 180

    180 = 180
