Question 969876: Computer monitor sizes are based on the length of their diagonal distance across the screen. For example, if you have a 35” monitor, this is measured by the length of their diagonal distance across the screen from one corner to the other. If a 35” monitor had a height of 21”, what would be the width across the monitor equal? Answer by macston(5194) (Show Source):

The diagonal is the hypotenuse of a right triangle with height and width as legs, so:
.
Let c=diagonal=35 in, a=height=21 in, b=width
. Subtract a^2 from each side. Find the square root of each side. Plug in values.
ANSWER: The width is 28 inches.
