    \[sinx = \frac{ opposite }{ hypotenuse }\] \[cosx = \frac{ adjacent }{ hypotenuse }\]

    hint: we can write this: \[\left\{ \begin{gathered} \sqrt {119} = 12\sin X \hfill \\ \hfill \\ 5 = 12\cos X \hfill \\ \end{gathered} \right.\]

    based on what @Michele_Laino wrote... divide 12 on both sides to have sin x and cos x by itself

    There isn't much left to do, michele_laino has gave you your equations now you're just one step away from completing it, I'm sure you can do the rest.
