Guy wire. How long is a guy wire reaching from the top of a 24ft ploe to a point on the ground 16 feet from the pole
What is the exact length?
what is the lenght approximated to three decimal palces?

draw your triangle
the legs are 16 and 24
or, 4*4 & 4*6
so, the hypotenuse (guy wire) is 4*sqrt(16+36) = 4*sqrt(52) = 8*sqrt(13)
