If the TV's diagonal is 17 and the width is 8 inches (crazy size for a TV), then we are looking at solving for the height using Pythagorean's Theorem because this is a right triangle situation. [tex] 17^2-8^2=a^2 [/tex] and [tex] 289-64=a^2 [/tex]. [tex] a^2=225 [/tex] so a = 15. The height of the TV is 15 inches.
