To find the length of the cable, we can use the Pythagorean theorem. The length of the cable is the hypotenuse of a right triangle, with the support cable as one side and the distance from the base of the pole to the anchor point as the other side.
Using the Pythagorean theorem, the length of the cable can be found:
c^2 = a^2 + b^2
where c is the length of the cable, a is the length of the support cable (20 ft), and b is the distance from the base of the pole to the anchor point (10 ft).
Plugging in the values:
c^2 = 20^2 + 10^2
c^2 = 400 + 100
c^2 = 500
Taking the square root of both sides:
c = √500
c ≈ 22.4 ft.
Therefore, the length of the cable is approximately 22.4 ft.
An electric pole has a support cable that is attached to the pole 20 ft. from the ground. The cable is anchored on the ground 10 ft. from the base of the pole. How long is the cable? Round to the nearest tenth.(1 point)
