The sum of the angles of a triangle is 180 degrees.
a + b + c = 180.
a + (a+10) + 2a = 180
3a + 10 = 180
3a + 10 - 10 = 180 - 10
3a = 170
a = 42.5 degrees
b= 52.5 degrees and c = 85 degrees.

In triangle abc, angle b is 10 degrees greater than angle a. Angle c is twice as much as angle A. what's the measure of each angle?
