Determine the forces in each member of the truss shown. Also find the values for any reactant forces

2. Relevant equations

F_{x}= 0

F_{y}= 0

3. The attempt at a solution

I set θ in the corner of J_{1}

tan θ=12/16

θ = tan^{-1}12/16

θ = 36.87

I set Φ in the corner of J_{3}

tan Φ = 12/9

Φ = tan^{-1}12/9

Φ = 53.13

This is where I began to falter. I could not figure out how to diagram everything out. If someone could just at least give me a diagram of where things are supposed to go, I can sum up the x and y forces by myself. This is pretty urgent, and I was absent for this class so my only help is messy notes from another student. This isn't in my textbook. Any help will be appreciated.
