Question 551574: The second angle of a triangle is 3 times as large as the first. The third angle is 12 degrees more than the sum of the other two angles. Find the measure of each angle. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! angle I x
Angle II 3x
Angle III = x+3x+12= 4x+12
x+3x+4x+12=180 ( sum of angles of triangle = 180 deg.)
8x+12=180
8x=180-12
8x=168
/8
x=21
angle I = 21
Angle II = 63
Angle III = 96
