title: How to count the X and Y coordinates of a point from the object's rotation (angle) and leg's length?
body: <p>Can anybody tell me how I can count the B point's coordinates (see attached image... or not as I am a new user...pf!). I know the arrow's rotation - so the angle (let's say it is -120), A's coordinates (0, 0) - A is the middle point of the arrow, and that the distance between A and B is 50 px.
  Thanks a lot!</p>
