in triangle ABC, the measure of angle B is twice the measure of angle A. the measure of angle C is 80 degrees more than that of angle A. find the measure of each angle.
~~~~~~~~~~~~~~~~~~~~~~~`

A + B + C = 180,

B = 2A,

C = A + 80 ----->

A + 2A + (A+80) = 180,

4A = 180 - 80,

4A = 100,

A = 100%2F4 = 25 degrees
