1. Let’s
assume that x=5 and y=5.
2. The
Pythagorean theorem states that the hypotenuse =
3. We
can use the Pythagorean theorem to show that the hypotenuse would be equal to
4. Now
if we increase x to 6, then y must go down to 4, and the hypotenuse would be
equal to
5. We can
see from the table below that the minimum would be at x=5 and y=5. Any change
would increase the length of the hypotenuse.
