Imagine this is in a coordinate system and the dotted line is in the x direction.

In order for the box to stay on the dotted line, the forces in the y direction must be equal.

We can find these forces using the magnitude of the forces and the sine ratio.

#125sqrt(3)sin(30)=125sin(x)#

#(125sqrt(3))/2=125sin(x)=>sinx=(125sqrt(3))/250=sqrt(3)/2#

#x=sin^-1sinx=sin^-1((sqrt(3))/2)=60^@#
