SK: JDoe's first shared image, http://www.mathwarehouse.com/trigonometry/images/sohcohtoa/sohcahtoa-all.png, contains most or all of the info you'll need to solve this problem. It's important that y ou know the definitions of the sine and cosine functions (as well as of the other four). To review: $$\sin \theta =\frac{ opp }{ hyp }, and.\cos \theta=\frac{ adj }{ hyp }$$

mathmale · Answer

You are to find sin x and cos x from the info in the illustration.  This means you can safely ignore angle y.

Look at angle x.  Which side of the triangle is opposite angle x?
Which side is the hypotenuse?
What is the length of the opposite side?
What is the length of the hypotenuse?

Then, what is the ratio sin theta = opp/hyp?
