## THIS USER ASKED 👇

**If the sin 90° = 1, then which statement is true? cos 0° = 1, because the cosine and sine are complements cos 90° = 1, because the cosine and sine are supplements cos 0° = 0, because the cosine and sine are complements cos 90° = 0, because the cosine and sine are supplements**

## THIS IS THE BEST ANSWER 👇

cos 0 ° = 1, because the cosine and sine are complementary

step by step explanation:

we are told that sin is 90 ° = 1

sine of any acute angle equals cosine of its complement.

cosine of any acute angle is equal to sine of its complement.

we are given

⇒

⇒

since we are given that sin 90 ° = 1

⇒

therefore choice is right.

cos 0 ° = 1, because the cosine and sine are complementary
