We are given :
m= 32.0 kg
g = 9.81m/s^2

We are looking for the Tension

We you look at the diagram you can see that the backpack isnt moving, it is in equilibrium , therefore the acceleration is 0. and we know that when the acceleration is 0 , the sum of all the forces in the system equals to zero.

For the x-components:
the sum of the F= 0
and Sum F = Tcos35 - T cos 35
recall the sum F =0 so 0 = Tcos35 - Tcos35 which doesnt really help so lets look at the y-components:

Sum F = 0
Sum F = 2Tcos35 - Fg ( we know that Fg = mg )
0= 2Tcos35 - mg
mg = 2T cos 35
mg / (2cos 35) = T
[(32)(9.81)] / (2cos35) = Tension = 273.37

thus, the tension of the rope is 273 N
