An angle measures 12°. Find its complement. Do not include units in your answer.

78

Step-by-step explanation:

complements = 90

x + 12 = 90

-12. -12

× = 78

If two angles are complementary,

then the sum of their measures is 90 degrees.

If two numbers add to 90, we can represent those numbers as x and 90 - x.

So we will call one of our angles x and its complement as 90 - x.

So we have 90 - 12 which is 78.

So the complement of a 12° angle is a 78° angle.
