I'm guessing the mass is 35kg?? I think you forgot to times mass by 9.81 to get mg (the weight)

that still equals 297 thats what i did
that still equals 297 thats what i did
ok its t(cos30) = 35 * 9.81
Not sure what you have done, but you should use Newton's second law whilst resolving the forces in the vertical direction.
ok its t(cos30) = 35 * 9.81
Yes.
