Help Solving a Stalled Car Problem

[jorge0531]

I would really appreciate some help with this problem.

1. A student's car stalls right in front of a speed bump while she is on her way to physics class. To pull it over the bump, she ties a cable to her bumper and to a nearby tree, and pulls with a force, F, of 73.0 lbs (325 N) at the midpoint in a perpendicular direction.
If θ is 11.0°, what is the size of the force pulling the car in lbs?

2. I know it must have something to do with finding the tension in the cable I just have no idea how so any help or hint would again be greatly appreciated.3. Maybe it has to do with Newton's second law of motion "F=ma" but the problem doesn't give me mass. I honestly have no idea what to do here.

… Maybe it has to do with Newton's second law of motion "F=ma" but the problem doesn't give me mass.

in questions like this, you can assume that the acceleration is zero

so the three forces on that "corner" of the rope must add to zero
