hehe not as far as I've heard of.

With only one known side and knowing it's a right angle, the other sides could be any value from nearly 0 to infinity and the angle between them could be in the range 0 < angle < 90

So, since there are many possible results, you cannot find a value for the hypotenuse if you don't know both the adjacent and opposite sides or one of those and the angle between it and the hypotenuse
