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)

Answer:

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°

Answer:

m∠A = 21°

m∠B = 84 °

m∠C = 75 °
