inclined plane problem?

Question

a guy wire runs from the top of a telephone pole 56 ft high to the ground and pulls on the pole with a force of 290 lbs what is the horizontal pull on the top of the pole?explain!!!!!!

Answer 1

There is not enough information and here is why.

In this case a force has both vertical and horizontal components. To find them you must have a relationship between at least two sides of a right triangle. We have only one side.
let
pole is ant a right angle to the ground
h - height of the pole
d - distance from the base of the pole to guy wire anchoring point.

then
A=arcTan (h/d)
Then the horizontal force
Fh=Fcos(A)
