 Question 513841: in a triangle ABC, angle B is four times angle A and angle C is 2 degrees less than 5 times angle A. Find the size of the angles. what is the size of angle A?Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!in a triangle ABC, angle B is four times angle A and angle C is 2 degrees less than 5 times angle A. Find the size of the angles. what is the size of angle A? ----- A + B + C = 180 B = 4A C = 5A-2 ---- Substitute for B and C and solve for "A": A + 4A + 5A-2 = 180 10A = 182 A = 18.2 degrees B = 72.8 degrees C = 89 degrees ============ Cheers, Stan H. ============
