Question 1158059: In triangle ABC, the size of angle B is 3 times the size of angle A, and the size of angle C is 13degrees less than 6 times the size of angle A.
find all the angles Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! angle A=x
B=3x
C=6x-13
The three add to 180 deg
so x+3x+6x-13=180
10x=193
x=19.3 deg angle A
3x=57.9 deg angle B
6x-13=102.8 deg angle C
