If the measure of an angle is twenty less than the measure of its complement, what is the measure of the angle?
velikii [3]
That angle would be 35 degrees. 

Complementary angles equal 90 degrees. So you can create an equation with x as the angle and its complement being x + 20. Set that equal to 90 and solve.
