An electric pole has a support cable that is attached to the pole 20ft. Form the ground. The cable is
attached to a point on the ground that is 10ft away from the base of the pole. The length of the support cable can be determined using the Pythagorean theorem.
Let the length of the support cable be x. According to the Pythagorean theorem, the square of the hypotenuse (the support cable) is equal to the sum of the squares of the other two sides:
x^2 = 20^2 + 10^2
x^2 = 400 + 100
x^2 = 500
Taking the square root of both sides, we get:
x = √500
x = 22.36
Therefore, the length of the support cable is approximately 22.36 ft.
