Let triangle ABC be a right triangle right angled at B and AB be the base of it. 
Assume BC to be the height of the pole and let it be x m.
Now AB will be the shadow. 
and angle A will be 60 
so tan 60 = perpendicular / base 
tan 60= BC/ AB 
root 3= x/ 2root3 
root 3 × 2 root3= x 
2× 3= x 
6 = x 
height of pole = 6m.
