Question

Ed and Al are pushing on a couch as shown in the picture and it doesn't slip.

Ed and Al are pushing on a couch as shown in the picture and it doesn't slip. Ed is pushing with a force of 307.2 N at an angle of = 50.5 degrees with respect to the vertical and Al is pushing with a force of 86.3 N at an angle of = 31.6 degrees with respect to the horizontal. If the couch has a mass of 73 kg and the coefficients of static and kinetic friction are s = 0.50 and k = 0.37, what is the magnitude of the force of friction exerted by the floor on the couch?

Not sure where to start, any ideas? Explanations/easy to follow steps would be amazing (I want to know how to do the problem come test time!) Thank you!
