Have a hard finding side b.

I'm stuck so far

just found the side You just found what side? Where is your work?

I don't even know if that is correct

What is it that you're not sure is correct? All I see is a diagram that you were given.

30 degrees is one of the special angles for which you're supposed to memorize sine and cosine. Do you have a textbook?

You ought to have been given the right-triangle trigonometric definitions for sine and cosine, in terms of adjacent side, opposite side, and hypotenuse.

Do you know the definition for cosine?

Also, the longest side is called the hypotenuse. That side is not "TAN". It should be labeled "HYP" for hypotenuse. :cool:
