Is there someone who knows how to calculate value "e" in added geometrical figures from a given "x" and "y" coordinate?

Attached are 3 different outcomes of this figure which were created in CAD. In CAD it’s easy to get value e with the given lengths but finding the proper equation is a different question. Dimensions are labeled in the figures and have in the example the length which is between (xxx).

Dimensions 1130.5, 878.78, 2002 and 1230.85 are for the legs with fixed lenghts. All other dimensions and angles can vary depending on dimension “x” and “y”

When trying to solve this I tried to use the cosinus rule but I keep missing 1 variable to solve the equation. Who is able to help?
