In triangle ABC, the size of angle B is 3 times the size of angle A, and the size of angle C is 12degrees less than 6 times the size of angle A. What are the angles?
angle A
angle B = 3A
angle C = 6A - 12 Added togehter they must equal 180 degrees for a triangle
A + 3A + 6A-12 = 180 Solve for A then B = 3A and C = 6A-12
