A volleyball net post needs a cable to support it. The hook to attach the is 4ft. above the court surface and the hook is in the floor is 3 ft from the base How long should the cable be
To find the length of the cable, we can use the Pythagorean theorem.
Let's assume the distance from the hook to the top of the post (where the cable will be attached) is represented by a, the distance from the hook to the base of the post is represented by b, and the length of the cable is represented by c.
According to the problem, a = 4 ft and b = 3 ft.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides.
Therefore, we can write the equation as:
c² = a² + b²
Substituting the given values, we have:
c² = (4 ft)² + (3 ft)²
c² = 16 ft² + 9 ft²
c² = 25 ft²
Taking the square root of both sides to solve for c, we get:
c = √(25 ft²)
c = 5 ft
Therefore, the cable should be 5 ft long.
