solve a triangle with only two known variables

hello all,

i don't think this is possible but does anyone know how to solve a right triangle when only one leg is known? i am mainly interested in the resulting hypotenuse of the triangle.

thanks in advance.

you will need to know another angle apart from the 90 degree or at least the size of another of the sides

that is what i was afraid of...

i was hoping someone had found some new triangle magic the world hadn't heard of yet.

If you know any tangent, cossen, sen, maybe.

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

You could also succeed if you were given the area of the triangle (as well as one side or one acute angle).
