Answer:

C. sin(90° - θ)

Step-by-step explanation:

A trig function of an angle equals the cofunction of the angle's complement.

The cofunction of  cosine is sine, and the complement of θ is 90° - θ.

∴ cosθ = sin(90° - θ)

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

\cos \theta

We need to find the correct cofunction identity for it.

Cofunction identities represent the relationship among the trigonometric functions.

The value of trigonometric function of an angle is equal to cofunction of its complement.

As we know that sine is a complement of cosine.

so, it becomes,

\cos \theta=\sin(90^\circ-\theta)

Hence, Option 'C' is correct.
