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 i
user100 [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
