Three strings, in the horizontal plane, meet in a knot and are pulled with three forces such that the knot is held stationary. The tension in string 1 is T1 = 2.9 N. The angle between strings 1 and 2 is q12 = 130° and the angle between strings 1 and 3 is q13 = 120° with string 3 below string 1 as shown.

2. Relevant equations

F=ma

3. The attempt at a solution

I am unsure. I tried finding two equations with two unknowns and then tried solving for one, but I no idea what to do. my free body diagrams aren't helping either. Could someone explain how my FBD would look or at least explain what equations I should have come up with? Thanks for any help.
