A tree casts a shadow that measures 5 m. At the same time, a meter stick casts a
shadow that is 0.4 m long. How tall is the tree?
Let the measure of the tree=x
The measure of the meter stick=1m
Shadow of the tree=5m
shadow of the meter stick=.4m
These are similar triangles, so the ratio of height/shadow of the tree=ratio of height/shadow of the meter stick.
x%2F5m=1m%2F.4m
5mx%2F5m=5m%281m%29%2F.4m
x=5m%5E2%2F.4m
highlight%28x=12.5m%29
Happy Calculating!!!
