[begining of code]
Disp "UNKOWN=X"
Disp "ENTER A"
Input A
Disp "Enter B"
Input B
Disp "Enter C"
Input C
If C=X
√(A² + B²)→C
If B=X
√(C²-A²)→B
If A=X
√(C²-B²)→A
Disp “Answer Is”
Disp “A”
Disp A
Disp “B”
Disp B
Disp “C”
Disp C

this program isn't going to work because x is a numerical value that is 0 by default. so if the user types in "x" for the variable they don't know, the calculator will interpret it as 0, and you'll have the problem i mentioned earlier. if another program you used stored a different value to x already, say, 14, your output is going to be seriously skewed because the calculator will interpret x as 14--NOT an unknown number.
if what i suggested didn't work, then you probably didn't implement it correctly. try this: replace all instances of "x" with pi. not just 3.14, i'm talking about the pi variable you get when you push 2nd ^. this way, in order to throw the program off the user would physically have to type 3.141592654 (assuming you're in float mode, where decimals don't get rounded).
so the first line would be disp "UNKNOWN=<pi character>" and your if statements would be if A=<pi character> then / if B=<pi character> then / etc.
