the box will not come down.


Since the angle of incline is 120degrees hence its obtuse angle.

the box will not come but actually fall down,may be thats not your required answer but actually thats happen as per your question.my own work

so that situation you are telling ,so you need to specify which angle you are telling is that the acute angle or the obtuse.

well its written that is comes down so to make the situation correct we should take the acute one ,but still tell what you want.
