Question

A telephone pole is 54 feet tall. A guy wire runs 79 feet, from point A at the top of the telephone pole, to the ground at point B. The base of the telephone pole is at point C. Triangle ABC is a right triangle.

How far is it from the base of the telephone pole to point B where the guy wire is secured to the ground? Round to the nearest tenth of a foot.

Answer 1

We can use the Pythagorean Theorem to solve this. The length of one leg is 54, the length of the hypotenuse is 79. Call the other leg x.

By the Pythagorean Theorem:

x^2 + 54^2 = 79^2

I think you can take it from there to solve for x
