Answer:
19.6ft (nearest tenth)
Step-by-step explanation:
Please refer to the attached photo for better understanding.
Given Length of Wire = BC = 22ft
Given Distance from Grounded Wire to Base of Pole = AC = 10ft
Length of Pole = AB
We can use Pythagoras' Theorem to find Length of Pole, AB.
By Pythagoras' Theorem,
[tex]c^{2} =a^{2} +b^{2} \\BC^{2} =AB^{2} + AC^{2} \\22^{2} =AB^{2} +10^{2} \\484=AB^{2} +100\\AB^{2} =484-100\\AB=\sqrt{384} ft\\=19.6ft (nearest tenth)[/tex]
