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

[Iceclover]

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.

 

[Maxwell]

theta = arccos(W/(F*d)) is how you'd find the angle given that eqn.
