1. The problem statement, all variables and given/known data
Find the tension in string 1

I don't get the same answer as the solution manual.

My attempt:
The y-component of string 2’s tension must equal the weight of the block.
The x-component of string 2’s tension must equal the tension of string 1.
T1=T2x=T2y/tanθ =23°

solution manual says 34 N.

Good.
Not sure what you did here (better to write the equations step by step), but I think you found that the tension in string 1 is about 23 N (not degrees!). Sounds right to me.

I'd say that was wrong.

tanθ=T2y/T2x
tanθ=mg/T2x
T2x=T1=mg/tanθ = 23 N (oops,not degrees!)

Thanks Doc Al! Just wanted to make sure I wasn't crazy!

Much better.

You are welcome.
