Problem
Find the degree measure of an angle whose complement is 25% of its supplement.
Solution
Solution 1
We can create an equation for the question, 
After simplifying, we get 
Solution 2
Let 
be the degree measure of the supplementary angle. Given that the complementary angle is 
of the supplementary angle, subtracting the complimentary angle from the supplement angle, we have {90^{\circ}} =
