$$\large \begin{array}{ccllll} (&12&,&5)\\ &\uparrow &&\uparrow \\ &x&&y \end{array}$$ thus |dw:1408396503470:dw| so... what's the hypotenuse? notice is a right triangle, so you can use the pythagorean theorem to get that keep in mind your SOH CAH TOA ,thus $$\bf cos(\theta)=\cfrac{adjacent\ side}{hypotenuse}$$

$\cos \left(\tan ^{-1}\left(\frac{5}{12}\right)\right)=\frac{12}{13}$
