Answer 2

5,4,3.

18 inches.

Answer 3

sqrt(30^2-24^2) = 18 inches

Answer 4

A tv or computer monitor is measured according to its diagonal or you measure the diagonal of the screen. So a 30 inch TV represents the diagonal of the rectangular screen of the TV. Therefore, if the diagonal is 30 inches and the width( which represents the base of the rectangle), then the height is solved using Pythagorean theorem.

                Solution: Base^2 + Height^2 = Diagonal^2

                               24^2 + H^2 = 30^2

                                          H^2 = 30^2 - 24^2

                                           H^2 = 900 -576

                                           h^2 = 324

                                           H = 18 inches

Answer 5

18 inches

30² - 24² = 324

900 - 576 = 324

square root of 324 = 18

height is 18 inches
