A frame hung against a wall is suspended by two wires attached to its upper corners.

If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0.75 of the weight of the frame? (Neglect any friction between the wall and the picture frame.)

2. Relevant equations

F=ma

w=mg

3. The attempt at a solution

I think it looks something like this:

It says .75 weight of frame, so I did the following to convert to N.

w=.75(9.8) = 7.35N

That is 7.35 on each side, and this is the part that get's me "if the tension in each wire is equal to 0.75 of the weight of the frame?"

I am lost, here. but for angle I think it should be something like this arc cos (14.7/7.35)

well at least i tried :D
