Tension with two strings and angles

[Ckrueger11]

Can someone help me with this problem? I am stuck.

So far I have:net Force (x) = T1cos30 - T2cos(θ) = 0

net Force (y) = T1sin30 + T2sin(θ) - 120N - 400N = 0 From equation 1 ---> cosθ = (T1cos30)/T2I attached a picture of the problem.

Not sure my y-equation is correct

How do I find T1 & T2

Split the two tensions into x and y components and then apply the laws for equilibrium:

∑F_x=0
∑F_y=0
∑M=0

I set the equations up and set them equal to zero but I don't know how to solve them for any of my unknowns.

You have 2 equations with 3 unknowns, you need to take moments about a point to get a third equation.
