Two angles are complementary. The measure of one angle is one fifth of the measure of its complement. Find the measure of the smaller angle.

We all know that complementary angles are angles that when added together, they will have a sum of 90 degrees. Here is the linear equation:
x=smaller angle
y or 5x = larger angle
y + x = 90 degrees
5x+x = 90 degrees

6x = 90 degrees
6x/6 = 90 degrees/6
x = 15 degrees
So:
The smaller angle = x = 15 degrees
The larger angle = y = 5x = 15 degrees(5) = 75 degrees
The 2 angles have degrees of 15 degrees and 75 degrees.
Check:
15 (5) = 75
75 =75, Correct

15 + 75 = 90
90 = 90, Correct
