An advertisement for a portable computer indicates it has a 13-inch viewing screen. This means that the diagonal of the screen measures 13 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. Width = __________ in. Height = __________ in.
