Megan constructed triangle ABC. In Megan's triangle,

mZA is represented by xº, mZB is 4 times greater than

mZA, and mZC is 30° less than 5 times m ZA.

mZA = x

mZB = (4x)

m2C = (5x - 30)

    21°, 84°, 75° are the angles

    Step-by-step explanation:

    Total angle in a triangle is 180.

    x + 4x + (5x - 30) = 180

    10x - 30 = 180

    10x = 210

    x = 21°

    Angles are:

    A: 21°

    B: 4 (21) = 84°

    C: 5 (21) - 30 = 75°
