Measure the distance of the diagonal (from one corner to the opposite corner) of the screen on your computer monitor to the nearest tenth of a centimeter or sixteenth of an inch. Measure the height of the screen along the verical as well. Use the Pythagorean theorem to find the width along the horizontal. I used sixteenth of an inch. The diagonal is 304/16 and the height is 192 sixteenths. My issue is that I can't at this time find what the pythagorean theorm is to get started with it. I know the formula should be a^2 + b^2 = c^2, which would be 304sixteenths^2 plus 192 sixteenths ^2 = c^2.

Thanks
