Solving Work Done by Pushing a Lawnmower

[fleur]

Homework Statement

A man pushes a lawnmower with a force of 200N. If the vertical component of this force is 80N how much work is done in pushing the lawnmower 6.0m horizontally?

Homework Equations

Work=force x distance

The Attempt at a Solution

Firstly I have to find the angle to the ground at which the 200N force is directed.
However i am not sure on how to do that.

Would the angle be 68 because inverse tan(200/80)

68 radians ? No, degrees I hope.
Never mind: once you have the angle, what are you going to use it for ?
And: Sketch ?
