When you search the web you will find a lot of hits. You just need to translate them to AutoIt.

To add to what Water just said you also should learn to ask sensible questions. In 2D (since you mentionned x,y only) determination of angle requires knowing an origin and two points or two lines. From this point of view, your question as it is doesn't make any sense.
