    i got the two equations but if i convert the sin thetas to decimals then the final answer wouldn't be accurate

    T1sin30+T2sin60=294 T1cos30-T2cos60=0

    In fact you don't need to convert them.Just try so solve a quadratic equation which you have found.

    you have to keep it on your calculator and round at the very end

    \[ \sqrt{3/2}T _{1}=1/2T _{2}\] and also \[1/2 T _{1}+\sqrt{3/2}T _{2}=294\]
