Question 271276: One angle of triangle is 20 degree larger than the smallest angle, and the third
angle is 6 times as large as the smallest angle. Find the measures of the three angles. Answer by CharlesG2(834) (Show Source):
You can put this solution on YOUR website! One angle of triangle is 20 degree larger than the smallest angle, and the third
angle is 6 times as large as the smallest angle. Find the measures of the three angles.
one angle = x
x + (x-20) + 6(x-20) = 180
x + x - 20 + 6x - 120 = 180
8x - 20 - 120 = 180
8x - 140 = 180
8x = 320
x = 40
x - 20 = 20
6(x-20) = 120
the 3 angles are 20, 40, and 120
