Forget that thread!

Hi,
I'm trying to calculate a postion of a moving object.
The known values are angles measured relative to the objects direction (left or right is unknown!) to other given points points.

How do I calculate the position of that object??

If you look at the example picture, the positon I'd llike to claculate is marked with the red symbol (the direction is depicted with the small pointer). The postion, that are known are marked by the green symbols (no. 1 to 4). The known values are in this example the angles measured from the direction of the object to the postions. In this example they are for No 1 61 degrees, No 2 28, Noo 3 124 and No 4 141.
