Cos 90° = 1

Step-by-step explanation:

Cos 90° = 1, Because The angles are complements

Using complementary angles, it is found that the correct statement is:

cos 90° = 0, because the angles are complements.

What are complementary angles?

Two angles are complementary if the sum of their measures is of 90º.

If two angles A and B are complementary, the sine of one angle is the cosine of the other.

In this problem, sin 0° = 0, and the complement of 0º is 90º, hence the correct option is:

cos 90° = 0, because the angles are complements.
