What is the angle of the rope in Physics 11 problem 10?

In summary, a sled with a mass of 845N is pulled a distance of 185m, requiring 1.20 x 10^4J of work to be done. The force used to pull the sled is 125N. To find the angle at which the rope is held, the equation theta = arccos(W/(F*d)) can be used. However, the answer of 1.0 degrees given by the user is incorrect.

Homework Statement


An 845N sled is is pulled a distance of 185m. The taskt requires 1.20 x 10^4J of work and is done by pulling a rope with a force of 125N. At what angle is the rope held


Homework Equations


W=Cos(of theta) Fd


The Attempt at a Solution


F=845N
d=185m
W=1.20x10^4J
F=125N
angle=?

I know how to do this question if I am given an angle but i don't really know what to do when I am supposed to be finding the angle.
