Question 322029
The lngth of tv sets are given by the diagonal measure.  

The height is the side measure (from top to bottom). 

The width is the bottom measure (from left to right).

The diagonla is 20.  Th width is 16 inches.

Use the Pythagorean Theorem to find the height.

Let h = height

16^2 + h^2 = 20^2

256 + h^2 = 400

h^2 = 400 - 256

h^2 = 144

{{{sqrt(h^2)}}} = {{{sqrt(144)}}}

h = 12

The height is 12 inches.
