Abby is buying a widescreen TV that she will hang on the wall between two windows. The windows are 36 inches apart, and wide scr
Musya8 [376]

Answer:

D < 40.2 inches

Step-by-step explanation:

The maximum width of the TV must be 36 inches. Since TVs are approximately twice as wide as they are tall, the maximum height is 18 inches.

The diagonal of a TV can be determined as a function of its width (w) and height (h) as follows:

d^2=h^2+w^2\\d=\sqrt{18^2+36^2}\\d= 40.2\ in

Therefore, the diagonal must be at most 40.2 inches.

Since the answer choices were not provided with the question, you should choose the biggest value that is under 40.2 inches.
