Question 782819: Angles A, B, and C are the angles in a triangle. Angle B is 2 times as big as angle A, and angle C is 12 degrees more than angle A. Find the measure of angle A in degrees. Answer by oscargut(2103) (Show Source):
You can put this solution on YOUR website! B = 2A
C = A +12
A+B+C = 180
Then
A + 2A + A + 12 = 180
4A = 168
A = 42
Answer: 42 degrees
