For the fun :

4^2 + 3^2 = 25
√(25) = ... (answer)

xD

That's not right D:, you calculate X at a whole other way, try thing below:

tan LA     3                 LA= tan-1(3/4)
------ =  --                             
    1        4

sin (tan-1(3/4))      3          AC=  3/sin (tan-1(3/4)) = 5
---------------  =  --
          1               AC

So X = 5!!  (I did like 20 minutes to calculate it at this way lol)

EDIT: But √(25) = 5 is also ok
