Description: Sal uses the Pythagorean theorem to solve a word problem about a fishing boat. Created by Sal Khan and Monterey Institute for Technology and Education. The main mast of a fishing boat is supported by a sturdy rope that extends from the top of the mast to the deck. If the mast is 20 feet tall and the rope attaches to the deck 15 feet away from the base of the mast, how long is the rope? So let's draw ourselves a boat and make sure we understand what the deck and the mast and all of that is.
