Answer
$ S 80^{\circ} W $
Work Step by Step
The trigonometric ratios are as follows: $\sin \theta= \dfrac{opposite}{hypotenuse}$ ; $\cos \theta= \dfrac{Adjacent}{hypotenuse}$ and $\tan \theta= \dfrac{Opposite}{Adjacent}$
The angle is from the vertical axis $ S $ to the line joining the point $ C $.
So, our required answer is: $ S 80^{\circ} W $
