Answer:
Step-by-step explanation: Let's say you have 2 supplementary angles, x and y
So x + y = 180
if x is 79.6 degrees less than the measure of a supplementary angle, then x = y - 79.6
Putting this into our x + y = 180 equation, we get
(y - 79.6) + y = 180
2y - 79.6 = 180
2y = 180 + 79.6
2y = 259.6
y = 259.6/2 = 129.8 degrees.
so x = 129.8 - 79.6 = 50.2 degrees.
See if it worked. x = 129.8 degrees, y = 50.2 degrees, x + y = 180 so we found the correct two angles!
