\n" ); document.write( "shadow that is 0.4 m long. How tall is the tree?
\n" ); document.write( "Let the measure of the tree=x
\n" ); document.write( "The measure of the meter stick=1m
\n" ); document.write( "Shadow of the tree=5m
\n" ); document.write( "shadow of the meter stick=.4m
\n" ); document.write( "These are similar triangles, so the ratio of height/shadow of the tree=ratio of height/shadow of the meter stick.
