Question 654181: In triangle ABC, angle B is three times as large as angle A. Angle C measures 20 degrees more than angle A. Set up an equation and solve. Find the measure of all three angles. Answer by solver91311(24713) (Show Source):
Let represent the measure of angle A. Then represents the measure of angle B, and represents the measure of angle C. The sum of the angles in any triangle is 180 degrees, so:
Solve for . Then calculate and
Add the three values to check your work.
