Dallas Buchanan · Answer 1

Let x = length of each pole.

The minimum length of each pole will be such that they poles are of equal length and symmetric about the vertical axis.

Therefore, consider a right triangle with height = 12, base = 8 and hypotenuse = x.

From the Pythagorean theorem,

x^2 = 8^2 + 12^2 = 208

x = 208^0.5 = 14.42 ft

Answer: Each pole is 14.42 ft long.
