A. 120 feet B. 17 feet C. 289 feet D. 23 feet

Respuesta :

The correct answer to the question above would be letter C. The diagonal piece of pipe would be 289 feet. I got this through drawing a line in the two opposite corners of the rectangle, giving me a right triangle. Then, i proceeded to using the pythagorean theorem (since two sides are given and the hypotenuse is the one missing.
