Question 143600
For every 1.9 m of distance the height decreases 2-1.6=0.4 m.
4*.4=1.6 the height of the girl's eyes.
So, 4*1.9=7.6m from in back of the girl the imaginary line touches the ground.
We have a right triangle. The base=24+1.9+7.6=33.5 m
x/33.5=1.6/7.6 proportion.
x=33.5*1.6/7.6
=134/19= 7 1/19 m height of tree
