1 Pythagorean Theorem 1. To make room for the new baby, Glenn is adding a room to his house. The blueprints for the addition indicate that the room should be a rectangle with dimensions of 9 ft wide by 12 ft long. Glenn just finished the framing and wants to make sure the room is a perfect rectangle before he starts putting up the drywall. To do this he measures the diagonals of the room, which should be the same length. How long should each diagonal be? 2. Two ships leave port at the same time. Ship X is heading due north and Ship Y is heading due east. Eight hours later they are 400 miles apart. If the Ship X had traveled 320 miles from the port, how many miles had Ship Y traveled? 3. If Z = 15 cm and X = 17 cm, what is the length of Y? 4. Jason accidentally locked himself out of his apartment, but remembered that he left a window open. The window is 16 feet above the ground. Since he works part-time at the local hardware store, he went to the store to borrow a ladder. There's a row of bushes along the edge of the apartment, so he will have to place the ladder 12 feet from the building. What length of ladder will Jason need to reach the window?
