Question 413325: Angle Measure.
In triangle ABC, Angle B is twice as large as Angle A. Angle C is 20 degrees more than Angle A. Find the measures of the angles.
I set up the problem as:
2A + A + 20= 360 but angle A ends up being 113.33, which solves to be a larger angle than 360.

a+2a+20=180
3a=160
a=53.33
2a=106.67
remember that triangles have a total of 180 degrees
