Question 601499: In triangle ABC, the size of the Angle B is 4 times the size of Angle A, and the size of Angle C is 20* less than 5 times the size of Angle A. What is the Angle of A, B, and C if the triangle is 180 degree? Answer by solver91311(24713) (Show Source):
I think you mean if the sum of the measures of the angles of the triangle is 180 degrees. Well, in the first place why say If -- what else could it be? Hence, the condition on the problem is redundant.
Let represent the measure of angle A. Then:
Solve for , then calculate , and . Check your work by adding the results for the three angles to verify that the sum is 180.
