How could the height of a tall pine tree be estimated without climbing it and measuring it?

math 
Reiny
measure the length of the tree's shadow
then measure the length of your own shadow
set up the proportion:
(height of tree)/(length of tree shadow) = (your height)/(length of your shadow)
height of tree = (your height)(shadow of tree)/(your shadow)
