Question

What lenght of cable is needed to anchor a 120 foot tall tower to its anchoring spot 50 feet from the base of the tower

Answer 1

This can be solved using the Pythagorean Theorem. You have the sides, and are looking for the hypoten√use ( c side)

a²+b²=c² Plug in values

120²+50²=c² Simplify

14400+2500=c²

16900=c² Take the square root of both sides

√16900=√c²

c=130 ft
