Step-by-step explanation:
Draw a Right triangle as the one shown in the image attached, where "x" is the distance from the base of the pole to the point in which the cable is attached to the ground.
In this case you need to use the Pythagorean Theorem. According to this theorem:
Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.
If you solve for one of the legs, you get:
In this case, you can identify that:
Substituting values, you get the following result:
