Question

NIGEL is looking to buy a TV. The space that NIGEL has available for a TV is 60 inches wide and 50 inches tall. A TV's size is advertised by its diagonal length.

To the nearest whole inch, what is the maximum TV size that NIGEL can buy?

Answer 1

78 inches

Explanation:

Well if we are assuming that the 60 inches and 50 inches are straight then we can use the Pythagorean theorem to do a^2 + b^2 = c^2, so so a=60 and b=50. so we do that we get 6100, and if we find the square root of that it will be about 78.1024, and that rounded is 78.
