In any triange, the sum of the measures of the angles is 180degrees. In triangle ABC, angle A is four times as large as angle B. Angle C measures 20degrees less than angle B. Find the measure of each angle.

ANSWER
A = 133.333333
B = 33.3333333
C = 13.3333333
WORK
A = 4B
C = B20
A + B + C = 180
   
(4B) + B (B20) = 180

6B  20 = 180
B = 33.33333

A is 4 times that
C is 20 less than that 
Sorry about the lines, I was expecting it to look like this:

Thanks Bartholomew!

in a triangle the sum of the angle is 180degrees. if angle A is three times angle B and Angle C is 10 degrees more than twice Angle A. Find the measures of the three anges to the newarest degree
