Asked by Jikyung

TV’s are usually measured along the diagonal of the screen. A 52-inch display has a

diagonal that measures 52 inches. If the height of the screen is 15 inches how wide is the TV?

Do we do 52 times 15? Or division? Or something else?

no, use Pythagoras

w^2 + h^2 = d^2 , width, length , diagonal
w^2 + 15^2 = 52^2
w^2 = 2704 - 225 = 2479
w = √2479 = appr 49.79 inches, I would say 50 inches
