Set up and solve an equation:
3(90-x) = (180-x). Then 270 - 3x = 180 - x, or 270 - 180 = 2x.
90 = 2x, so x = 45 deg.
Is this true? 3(90-45) = (180-45)? If so, x = 45 degrees is correct.

x = 1, y = -1, and z = 2
The dollar amount of each monthly payment is interest
7,865.87÷120=65.55
The percent of the total payments is total interest
(7,865.87÷27,865.87)×100=28.2%
