Im doing a physics equilibrium problem and I need to solve this equation:(adsbygoogle = window.adsbygoogle || []).push({});

900cos(x)+600cos(45+x) = 0

(the angles are in degrees)

What would be the best way to analytically solve this kind of equation? I tried using the sum-difference formulas but it wasn't able to solve for x.

Thank you very much
