A certain television is advertised as a 76-inch TV (the diagonal length). If the width of the TV is 66 inches, how tall is the TV? Round to the nearest tenth of an inch.

The most common TV sizes are 55, 65, 75, 85 inches. Many people are interested in what screen size the TV or monitor will have depending on the diagonal, as the diagonal does not give much information, moreover, we used to use old TV standards, with the size of the TV with an aspect ratio of 3×4.
