First, before we can even help you, you need to show your attempt at the solution. Second, whether or not you're a "drawing kind of guy", you'll have a difficult time doing a lot of physics problems without first drawing a free-body diagram. So, draw a free-body diagram and then show your attempt at a solution!

Show what you tried so people can help with what you are misunderstanding.

If you have no idea at least try to draw a picture for yourself, it will help.

You have a vector and you have its direction, now you just need to break it into an

x and y component. The x an y form the legs of a triangle and the Net vector is the

hypotenuse. See what you get.
