If the complement of a certain angle is five times the measure of that certain angle, then what is the measure of that certain angle? Answers.
A) 45°  B) 30°  C) 22.5°  D) 18°  E) 15°
Thecomplementof angle A is the angle which, when added to angle A, gives 90 degrees. The two acute angles of a right triangle are complements, for example.   The original angle is x, so the complement is 5x, and together, these add up to 90 degrees.   x + 5x = 90   6x = 90   x = 15°   Answer = (15°)
