Question

Best Buy is selling 55 inch HD TV’s. This measurement is the diagonal distance across the screen. If the screen measures 48 inches in width, what is the actual height of the screen?

Answer 1

To find the actual height of the screen, we can use the Pythagorean theorem.

Let the actual height of the screen be h.

Using the Pythagorean theorem:

(h^2 + 48^2) = 55^2

h^2 + 2304 = 3025

h^2 = 721

h = √721

h ≈ 26.85 inches

Therefore, the actual height of the screen is approximately 26.85 inches.
