Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.

An acute angle

90 - (2x - 3)

Complementary

Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle.Right Angle: An angle whose measure is 90 degrees is called right angle.Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle.Straight Angle: An angle whose measure is 180 degrees called a straight angle.Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle.Complete Angle: An angle whose measure is 360 degrees is called a complete angle.Zero Angle: If the measure of an angle is zero it is called a zero angle.
