Question 261353: The first angle of a triangle is half the measure of the second. The measure of the third angle is 40 degrees more than 4 times the measure of the first. Find the measure of each angle.

Let the first angle be A, the second is then 2A and the third 4A + 40.
Total of the angles is 7A + 40 = 180
So 7A = 140
A = 20, B= 40, C=120 degrees
