Answer:
Step-by-step explanation:
There are two possibilities here:
1) The two numbers are the legs of the right triangle. Then the hypotenuse is ...
√(9^2 +41^2) = √1762 ≈ 41.9762
__
2) The length 41 is the hypotenuse. Then the other leg is ...
√(41^2 -9^2) = √1600 = 40

Comment on Pythagorean triples
I find it somewhat interesting that for any odd number n, one Pythagorean triple involving that number is ...
(n, (n^2 -1)/2, (n^2 +1)/2)
For n=9, the triple is (9, 80/2, 82/2) = (9, 40, 41).
Along these lines, ones commonly seen in math problems are ...
(3, 4, 5), (5, 12, 13), (7, 24, 25), (9, 40, 41), (11, 60, 61)
