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)
500 ft.
17.3 ft.
22.4 ft.
300 ft.
Using the Pythagorean Theorem, we can find the length of the cable.
Let x be the length of the cable.
Using the Pythagorean Theorem: x^2 = 20^2 + 10^2
x^2 = 400 + 100
x^2 = 500
x ≈ 22.4 ft.
Therefore, the length of the cable is approximately 22.4 ft.
So, the answer is 22.4 ft.
