A smaller, clearer diagram would be helpful.

Can you obtain the "horizontal" and "vertical" components of each force?

fairly easy to see $\alpha = 30^\circ$

$\displaystyle \sum F_x = 10\cos(60)+20-10\sqrt{3}\cos(30) = 10$

$\displaystyle \sum F_y = 10\sin(60)+0-10\sqrt{3}\sin(30) = 0$

... what now?
