Javier bought a new television for his apartment it is 40 inches wide and 30 inches tall find the diagonal length of the television

To find the diagonal length of the television, we can use the Pythagorean theorem:

Diagonal length = √(width^2 + height^2)

Given that the width is 40 inches and the height is 30 inches, we can substitute these values into the formula:

Diagonal length = √(40^2 + 30^2)
= √(1600 + 900)
= √2500
= 50 inches

Therefore, the diagonal length of the television is 50 inches.
