Finding the angles

Question

One angle in a triangle has a measure that is 25 less than twice the smallest angle. The measure of the third angle is 50 degrees more than two times the smallest angle. Find the measures of each angle.

Answer 1

x=2s-25

y=50+2s

x+y+s=180

2s-25+50+2s+s=180

5s=155

s=31 degrees

x=37 degrees

y=112 degrees
