Let x be the measure of the smaller angle.
Then the measure of the larger angle is 2x-9 degrees.
The sum of the measures is 90 degrees, since the angles are complementary.
x + (2x-9) = 90 degrees.
Simplify and find x
3x = 90 + 9
3x = 99
x = 99/3 = 33.
ANSWER. The smaller angle is 33 degrees.
The larger angle is 2*33-9 = 57 degrees.
