Answer:
Let x be the measure of the angle. The complement of the angle is 90 - x degrees. The problem states that the measure of the angle is 18 degrees less than one-half of the measure of its complement. This can be written as:
x = (1/2)(90 - x) - 18
Solving for x gives:
x = 36 degrees
Therefore, the measure of the angle is 36 degrees.
The expression that would equal x is:
(1/2)(90 - x) -18
