It could either be

sqrt(16^2 + 12^2)

Or

sqrt(16^2 - 12^2)

depending on which 2 sides you've been given.

a,16in; b, 12in So the third side by custom is c the hypotenuse.
c^2 =a^2+b^2
c = +/- sqrt(16^2+12^2)
c= sqrt(400) = 20
We reject the answer -20 because a triangle cannot have a side of negative length.

Assume the missing side is the hypotenuse; then by our old friend Pythagoreus:
a^2 + b^2 = c^2, where c is the missing side
c = sqr[a^2 + b^2] = sqr[16^2 + 12^2] = sqr[400] = 20

It's either sqrt(16^2 + 12^2) = 20

or sqrt(16^2 - 12^2) = 10.6 (to the nearest 10th)

I'm not sure yahoo answers is the necessarily the way ahead for doing homework. If you don't understand the problem ask your teacher.
