There is a weight of 254.8 Newtons hanging from two ropes. One rope makes an angle with the ceiling with 71 degrees, and the other rope makes an angle with the ceiling with 28 degrees. What is the tension in each rope (use triangle trig, again pic is located below)?

thanks in advance. I had 269N and 543N for the ropes, but I am not completely sure.

Let A = ten of rope at 28 deg angle from ceiling
B = ten of rope at 71 deg angle from ceiling
Sum forces in x direction
A cos 28 = B cos 71
sum forces in y direction
A sin 28 + B sin 71 = 254.8
Solving for A & B
B = 254.8/ (tan28 x cos 71 + sin71)
A = B cos 71/ cos28
you crunch the numbers.
