Hey i've come across the following two equations and was just wodering if I could get some help solving them.
(1) 578cos(40) - x - xcos(y) = 0
(2) 578sin (40) - xsin(y) = 0
All help appriciated. Thanks.

I would probably look at each equation and make the the subject.
(1) x = 578cos(40)/(1+cos(y))
(2) x = 578sin(40)/sin(y)
Then making 578cos(40)/(1+cos(y)) = 578sin(40)/sin(y)
You now only have one variable. now re-arrange to elimate
578cos(40) and 578sin (40) and you should have
tan(40) = sin(y)/(1+cos(y))
From here you should try and find some funky trig identityto seal the deal.
