yeah i mean the problem itself is slightly underdefined because there are two possible solves, one where you rotate down and one where u rotate up

but it’s actually solved with a quadratic equation so u end up with both points of intersection

here are all the intersections visualized

here’s the file that has all the math for u

and like sure this could all be done with trig but this seemed cooler
