Answer 1

Answer:

$h=24\ in$ is the height of the TV screen.

Explanation:

Given:

diagonal of TV screen, $d=40\ in$

width of TV scree, $w=32\ in$

As we know that the TV screen is rectangular in shape so including its height and with along with the diagonal forms a right angled triangle in which the diagonal is the hypotenuse of the triangle formed so.

$h=\sqrt{d^2-w^2}$

$h=\sqrt{40^2-32^2}$

$h=24\ in$ is the height of the TV screen.
