Answer:

Fr = 55 [N]

Explanation:

We must perform a free body diagram to understand the forces acting on the couch. In the attached image we see the force that Jack exerts just like that of Rob acting in the same direction.

We must perform a summation of force on the X-axis, to determine the resulting force.

∑Fx = Fr

Fr = 30 + 25

Fr = 55 [N]
