question 34

Multiple Choice

An advertisement for a portable computer indicates it has a 17-inch viewing screen. This means that the diagonal of the screen measures 17 inches. If the ratio of the height to the width of the screen is 3 to 4, we can represent the height with 3 x and the width with 4 x , and then use the Pythagorean theorem to solve for x . Once we have x , the height will be 3 x and the width will be 4 x . Find the height and width of this computer screen to the nearest tenth of an inch.

• A)Width = 13.6 in.; Height = 10.2 in.
