4^2 + 3^2 = 25
√(25) = ... (answer)

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) _O-

EDIT: But √(25) = 5 is also ok  8)7

Theorem pythagoras

ab2 + BC2 = AC2
16 + 9 = 25
AC = ?25
AC = 5

Simple!

P.S. hehe

Edit: Wooooooooooops didn't see XanLand's post

Woops. Didn't read :p

Anyway... why do it your way? Too long O+

why do it with goneometrie (sinus/cosinus/tanges) If u know ab AND bc??? pythagoras is MUTCH faster
a^2=b^2=c^3
goneometrie is only nesecerly when u only know the angle of A/B/C and one line's lenght.....
