Question 986929: If the sum of the measures of two angles is 90 degrees, the angles are complementary. Thus, if the measure of an angle is A degrees, the measure of the compliment is (90 - A)degrees. Find an angle whose measure is 3 greater than twice the measure of its compliment.

.
Let x be the measure of the unknown angle (in degrees).

Then the measure of its complement is (90� - x), and we have an equation

x - 3 = 2(90-x).

Solve it:

x - 3 = 180 - 2x,

x + 2x = 180 + 3

3x = 183

x = = 61.

Answer. 61�.
