23 Baseball Diamond Cameron is a catcher trying out for the school baseball team. He has played baseball in the community and is able to easily throw the ball from home plate to second base to throw out a runner trying to steal second base.

24 However, the school baseball diamond is a regulation size field and larger than the field he is accustomed to. Will he be able to consistently throw out runners trying to steal second if he is able to throw the baseball 130 feet?

36 A telephone pole is 17 feet tall
A telephone pole is 17 feet tall. The wire that runs into the ground to connect to a house is 8 feet away from the base of the pole. How long is the wire that runs into the ground? Numero 3

37 A diver is 9 feet away from a buoy when he sees a starfish directly underneath the buoy. If the starfish is 12 feet under the buoy, how far will the diver need to swim to reach the starfish? Numero 4

38 Exit Ticket Draw a picture to represent the situation. Then, solve for the missing side. A spider leaves his hole in the wall and travels 8 meters along the floor, then turns 90Β° east and continues 6 more meters. At this point, he wants to return to his hole in the wall so he does not get squished. How far must he travel to avoid getting squished? 𝟏𝟎 π’Žπ’†π’•π’†π’“π’”

39 Warm Up Solve the following problem by drawing a picture to aid in understanding. Use the Pythagorean Theorem to solve for the missing hypotenuse. One end of a ladder is four feet from the base of a wall. The ladder touches the wall 10 feet up. How long is the ladder? 𝑓𝑒𝑒𝑑
