A friend of mine solved these pair of inverse trig equations simultaneously, claiming he did it with high school maths.
Well, I have a similar background ( & am a keen puzzle solver ) & could get nowhere with them !
Here they are :
ArcTan (8/x) = ArcCos ((x+y)/20)
ArcTan (8/y) = ArcCos ((x+y)/30)
Solve these inverse trigonometric equations for x & y
( I will be extrememely embarrased if the method is trivial, so please forgive me if I've wasted your time )
