Answer:

The third option.


cos(Q)=(RQ)/(PQ)

Explanation:

SIN is opposite over hypotenuse.

COS is adjacent over hypotenuse

Therefore


sin(P)=(RQ)/(PQ)

Then we have 4 options.

It is not the first option beacause we can't determine which side is adjacent to the angle.

The second option


sin(Q)=(RP)/(QP)

The third option


cos(Q)=(RQ)/(PQ)

It is not the fourth option beacause we can't determine which side is opposite to the angle.

Finally we see that


cos(Q)=(RQ)/(PQ)

and


sin(P)=(RQ)/(PQ)

are equivalent.
