(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Angular tension on a hanging body

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

"In the diagram (see link), the tension on FT1 is 200N, angle measurements given are 50 deg and 30 deg left to right. What is the tension in FT2? What's the mass of the box?"

(^diagram of problem^)

3. The attempt at a solution

I've worked out the FT2 value by making 200cos50=FT2cos30; getting a final number of 148.445N (correct according to answer sheet).

Solving for the mass, I've added the two 'y direction forces' which should equal Fg times some mass. Thus, 200sin50+148.445sin30=9.8(M)

which comes out to M= 23.207 Kg. The answer on my worksheet is "15.4kg" so apparantly I've done something quite wrong. Any help would be much appreciated, thanks a bunch.
