    Answer:

    30 and 60

    Step-by-step explanation:

    Let x represent the first angle

    (x) the sum of the first angle plus twice of the second angle 2(90 – x)

    x + 180 – 2x = 150

    180 – 150 = 2x – x (we export like terms to the same side of the equation)

    30 = x is the measure of the first angle and since the second angle is complementary to this the measure of the second angle is 90 – 30 = 60
