It's been too long since high-school algebra for me to remember what a
hypotenuse is, but Joe C.'s formula is correct.
Remember:gradient is not the same as angle.
For example: A 100% rise (rising 100 feet for every 100 feet in
distance) would be seen as a 45-degree angle when viewing the profile
of the hill from the side.
