Question

The value of sin35∘ is equivalent to which value?

A. cos65∘
B. cos55∘
C. cos90∘
D. cos45∘

Answer 1

I think is b hope it helps

Answer 2

B

Explanation:

We can use the following co-function identity:

`\sin(x)=\cos(90-x)`

Substuting 35 for x yields:

`\sin(35)=\cos(90-35)`

Subtract:

`\sin(35)=\cos(55)`

Hence, our answer is B.
