Complete the following statement: if the sin 90° = 1, then = 1

If the sin 90° = 1, the cos 0° = 1.

That is because sine and cosine of the complement angles are equal.

Hope tthis helps :)s

90° ; 1 over 2

0° ; square root 2 over 2

90° ; square root 3 over 2

0° ; 1

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
