Question

What is the length of the hypotenuse of a right triangle with leg lengths of 8 inches and 15 inches?

Answer 1

hypotenuse^2 = 8^2 + 15^2
hypotenuse^2 = 64 + 225 = 289 = 17^2
therefore hypotenuse = 17 inches

Answer 2

use the pythagorean theorem
c square= a square = b square
c square= 8 square + 15 square
c square= 64+225
c square= 289
c= square root of 289
c=17
( c stands for hypotenuse a&b stands for length)
