Ann is a construction worker, and she is preparing to have concrete poured at her construction site. Each corner is designed to
be a 90° corner. Using a tape measure, she takes measurements from the corners, marks a point, and then measures diagonally between the points to see if the corner is 90°. Which of the following sets of measurements would indicate that the corner she measured is 90°? Select all that apply. 6 feet, 8 feet, and 10 feet
6 feet, 8 feet, and 12 feet
9 feet, 12 feet, and 14 feet
9 feet, 12 feet, and 15 feet
12 feet, 16 feet, and 18 feet
12 feet, 16 feet, and 22 feet
Micha is an IT engineer and is adding a Wi-Fi range extender to an office. His Wi-Fi router base is located in a hallway, and he needs to know how far away the extender is, but he cannot measure directly because a wall is in his way. Using the Pythagorean theorem, he measures straight down the hall toward the door, which is 4 meters. He then turns 90° and measures through the doorway 4 meters to the extender. How far away is the extender from the router base, rounded to the nearest tenth?
