I need some help with this specific question. In a computer catalog, a computer monitor is listed as being 19 inches. This distance is the
diagonal distance across the screen. If the screen measures 10 inches in height, what is the
actual width of the screen to the nearest inch?
* I'd appreciate if I not only got an answer but an explanation too. Thanks :]

Use the Pythagorean theorem?
d^2=h^2+w^2
19^2=10^2+w^2

But how would you do it using
A^2 + B^2 = C^2 ?

Lord. It is the same thing. Letters don't matter.
diagonal^2=height^2 + width^2
