Thank you for your help in advance! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! let x be the size of angle A, then
:
x + 5x + 4x-7 = 180
:
10x = 187
:
x = 18.7
:
*******************************
Angle A = 18.7 degrees
Angle B = 93.5 degrees
Angle C = 67.8 degrees
