I am just confused on how to do this question. A 37-inch TV is 37-inches diagonally across the screen. Which of these dimensions best describes a 37-inch TV? A. 15 x 34 B. 16.5 x 32 C. 17 x 28 D. 17 x 32

Given that,

A TV is 27 inch diagonally across the screen.

To find,

The dimensions that best describes a 37 inch TV.

Solution,

Let a and b are length and width of the TV. Let c be the diagonal. Using Pythagoras theorem,

If dimensions are 15 x 34,

If dimensions are 16.5 x 32,

If dimensions are 17 x 28,

If dimensions are 17 x 32,

It is clear that if dimensions are 15 x 34, the diagonal is 37 inches. Hence, the correct option is (a).

since both sides equal, there are infinitely many olutions.
