Thanks to all of you! Even the mormon for the groaner!
The last time I had to know the square of something, I calculated it on my
sliderule.
Thanks again

It's been way too many years since I was in a math class and need help.

If I have a triangle that has one side at 39ft, the 2nd side is 37 ft. and
they meet at a right angle, how long is the third side?
Many thanks!
