find two angles such that the angles are adjacent and form an angle of 120 degress. the larger is 20 degrees less than three times the smaller.
-------------------
Equations:
x + y = 120
x = 3y - 20
------------------
Substitute to solve for "Y":
3y -20 + y = 120
4y = 140
y = 35 degrees
------------------
x = 120-y
So, x = 120-35 = 85 degrees
