draw free body diagram and A and B please. picture is pretty clear! Block is labeled A (under A is 25 degrees) above is 45 degrees and F pulling down is 50 degrees

2. In the figure, the crate A weighs 80 lb, the angle of the incline plane is 25° and the
coefficient of static friction between the crate and the incline plane is 0.30. The
coefficient of static friction between the rope and the fixed cylinder is 0.10. The left
segment of the rope makes an angle of 45° with the horizontal and the right segment
makes an angle of 50° with the horizontal as shown.
(a) Draw the FBD of the crate showing all the forces acting on it.
(b) Calculate the tension in the cable segment connected to the crate.
(c) Calculate the force F with which a worker must pull on the rope to start the
crate moving up the incline plane.
