I bought this truck crane for my dad. I want to calculate the mechanical advantage of it.

I know how to calculate the mechanical advantage of a hydraulic jack and of a lever but I am not sure about where they connect to each other. When the jack lengthens it rotates back so the different angles change. How do i calculate that? Where do i start. Does it involve the law of cosines and calculus or something simpler?
