Gas Spring Calculation Help

[ESTinker]

Trying to learn about gas springs and I'm not seeing how to get this angle for a gas spring angle to sum the moments at the hinge by the gas spring force.

No issue with it flat but say as an example ie. its is rotate at 10° then how is this angle calculated to sum the moments?

Would appreciate any help, probably some trig that I can't remember.

I don't know if this may help you or not:

just geometry ?

this is a classic "three force body" ... the three forces are weight, actuator force and pivot reaction (closes the force polygon ... no, not a dead parrot)
