an ant starts moving in a direction,after moving x direction she turns left by making an angle 120d,again moving x direction she turns right by making an angle 120d .distance between initial and final point is 9unit calculate x....!!!

  Assume ant is moves x distance frm east to west, n takes 120d turt to left, again moves x distance. From that pt it takes 120d turn to right,then ti moves x distance.
  Use sine n pythagoras Thm
  9^2=(5/2)x^2+root(3)/2^2*x^2
  x=9/root(7). i am nt sure, just check it
