Question

an overhead wire stretches from the service drop that is 20 ft from the ground, on a building to an insulator on a pole 35 ft from the ground. how long is the wire if the pole and building are 48 ft apart? (assume ground is level.) round answer to tenths.

Answer 1

50.6 ft

Explanation:

We can use the pythagoreas theorem to solve this problem.

If the service drop is 20 ft from the ground and the insulator is 35 ft, that means that the insulator is 15 ft higher than the service drop.

a² + b² = c²

15² + 48² = c²

255 + 2304 = c²

2559 = c²

√2559 = c

50.6 ≈ c
