1. The problem statement, all variables and given/known data

A box is hanging with two wires. (Refer to diagrams). Find the two tensions.

My first question is, if the two diagrams are different situations that will lead to different answers? Personally I don't think they would... since the x coordinates still have to equal zero, with the same angles... but I'm not exactly sure, can someone please clarify the concept behind this?

2. Relevant equations

T1*sin56 + T2*sin45 - 35N = 0

-(T1*cos56) + T2*cos45 = 0

3. The attempt at a solution

Prepared for substitution

T2 = T1(cos56)/cos45

T1(sin56) + T1(sin45)(cos56)/(cos45) - 35N = 0

T1(sin56 + sin45*cos56/cos45) = 35N

Solved for T1 = 25N.

Plugged in and got T2 = 20N.

So based on those equations I get T1 = 25N, and T2 = 20N... but the answer key shows a way different answer so I am confused. Could it be that the answer key is wrong? Or maybe it is because of the two different situations I've shown above? I'm use to doing problems like diagram 2, but for this question it is shown like diagram 1?

Please let me know if I made a mistake, this is driving me crazy.
