Answer:

  C.  cos(31°) = RS/24.8

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the adjacent side and the hypotenuse and the trig function of an angle:

  Cos = Adjacent/Hypotenuse

In the given triangle, the side adjacent to the 31° angle is RS. The hypotenuse is marked as 24.8. So, the relationship you seek is ...

  cos(31°) = RS/24.8 . . . . . matches choice C
