Answer:

  b. 90 -n

Step-by-step explanation:

The sum of an angle and its complement is 90 degrees. If c represents the complement, this means ...

  n +c = 90

  c = 90 -n . . . . . . . . . subtract n from both sides of the equation

The expression 90 -n can be used to find the complementary angle.
