From this we should be able to determine distance relative to the IR beacons (x and y) and relative angle to the line between the 2 beacons. If anyone could explain this out to us we would really appreciate it. Thanks
You cannot triangulate absolute position this way. You only know one angle and one side of the big triangle (you dont know the distance from either of the beacons to you!). You will have to devise a way to compute the distance from you to the beacon (create another triangle that you CAN triangulate) before you could determine absolute position.
