Use the Pythagorean Theorem. Draw the picture, if you're not sure where the given values go.

You have "a<sup>2</sup> + b<sup>2</sup> = c<sup>2</sup>", where "a" and "b" are the legs and "c" is the hypotenuse. You say you have drawn the picture, so you can see from that which are the (shorter) legs and which is the (longer) hypotenuse.

Please clarify where you are stuck. Thank you.

So maybe i should say I don't understand how to draw the picture, because if i did that then I would know which numbers to plug in where??

Yes, 12 is correct. Good work :idea:
What you really had was a right triangle, hypotenuse = 13, one leg = 5.
