Question 713291:
In triangle ABC, the size of angle B is five times the size of angle A and the size of angle C is 16° less than 4 times the size of angle A Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! B=5A
C=4A-16
A+B+C=180
A+5A+(4A-16)=180
10A=180+16
10A=196
A=196/10
A=19.6 DEGREES.
B=5*19.6=98 DEGREES.
C=4*19.6-16
C=62.4 DEGREES.
PROOF:
19.6+98+62.4=180
180=180
