the sum of the measures of two supplementary angles exceeds the difference of their measures by 116 degrees. find the measure of each angle.
-----
Eqution:
x + y = 180
x+y = (x-y) + 116
======================
x = 180-y
---
Substitute and solve for "y":
180 = (180-y-y) + 116
-2y = -116
y = 58 degrees
----
Solve for "x":
x + 58 = 180
x = 122 degrees
