Please any help would be great.






A guy wire is needed to secure a pole. You have a wire the length 25 feet which could be used. The latch to which it will be secured on the ground is 10 feet from the base of the pole. How high up the pole will the guy wire be attached if you choose to use it.


Please help

We will assume that the pole is situated perpendicular to the ground. This problem can then be solved using the Pythagorean theorem.

a^2 + b^2 = c^2

Let a = 10 ft, Let b = the length of the pole from the ground to where the wire is connected and let c = 25 ft.

Therefore, 10^2 + b^2 = 25^2

100 + b^2 = 625

b^2 = 525

b= 22.91 ft (rounded to two decimal places)
