2 Pythagorean Theorem Review Missing Leg. Directions: Using the Pythagorean Theorem, find the missing side length for each right triangle. 3) The accompanying diagram shows a kite that has been secured to a stake in the ground with a 20-foot string. The kite is located 12 feet from the ground, directly over point X What is the distance, in feet, between the stake and point Xl 4) The opening ofa tent is shown below. How wide is the opening ofthe bottom? a) SimplifY to simplest radical form in feet. b) Approximate the ladder's length to the nearest tenth of a foot. 5) leg = 12, leg =, hypotenuse = 14
3 Use the Pythagorean theorem to solve each problem. A tent is supported by a guy rope tied to a stake, as shown in the diagram. What is the the length of the rope? If the supporting stake in Problem 1 were 15 feet from the tent, and an B-foot tent pole were used, what would be the length of the guy rope? I Stephanie is planning a right triangular garden. She marked n two sides tliat measure 24 feet and 25 feet, What is the length of side n? 24 feet 1'1 II" A builder needs to add diagonal braces to a wall. The wall is!~l '.6feet wide by 12 feet high.
