The given data is theta 1 is equal to 37 .0 degree, theta 2 is equal to 53 .0 degree and theta 3 is equal to 56 .0 degree.

Now drawing the free body diagram, we have the force acting downwards is the tension t3 and similarly there is going to be an exertion in the upward direction also.

If the mass of this body is 4 kg, then the tension t3 is mg and the mass value into gravity gives us the tension t3 as 39 .1 newton.
00:49
Drawing the free body diagram with respect to the figure given, this is the tension t2, tension along the string t1, the tension along the string t3 and the angles are given as 37 degrees and 53 degrees respectively.

Similarly for the second body of mass 9 kg, these are the directions of the tension and t3 again is here is given as 88 newton and drawing the free body diagram with respect to the diagram given, we have this as 56 degree, the tension t1 and the tension t3 and here the tension is along t2.

Now with this free body diagram in mind, we have the summation of the forces along x direction as t2 cos 53 degrees minus t1 cos 37 degrees is equal to 0...
