Question

Best Buy is giving you a free t.v. with purchase of a new refrigerator. The t.v. is 30 inches tall and 48 inches wide. How big is the tv, meaning how long is the diagonal of the television screen? Round your answer to the nearest inch.

Answer 1

Answer:

57 inches

Step-by-step explanation:

The height, width, and diagonal of the TV screen form a right triangle.

Use the pythagorean theorem, a² + b² = c², and solve for c, the hypotenuse/diagonal of the TV.

a² + b² = c²

30² + 48² = c²

900 + 2304 = c²

3204 = c²

56.6 = c

Round this to the nearest inch:

56.6

= 57

So, the diagonal of the TV screen is 57 inches
