Question 345195: the sum of the angles is 180 degrees. in triangle ABC angle A if four times as large as angle b. angle measures 20 degress less than angle b. what is each angle Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! i'LL ASSUME THAT [C] IS 20 DEGREES LESS THAN B.
A+B+C=180
A=4B
C=B-20
4B+B+(B-20)=180
6B=180+20
6B=200
B=200/6
B=33.33 ANS.
A=4*33.33=133.33 ANS.
C=33.33-20=13.33 ANS.
PROOF:
133.33+33.33+13.33=180
180~180
