Similar triangles.
\n" ); document.write( "Height of first tree/ x (Unknown height of other tree)
\n" ); document.write( "= Length of first shadow/ Length of second shadow
\n" ); document.write( " 12/x = 33/20
\n" ); document.write( "Cross multiply
\n" ); document.write( "33x = 240
\n" ); document.write( " x = 240/33
\n" ); document.write( "x = 7.27 yds.
\n" ); document.write( "This is the height of the second tree.
\n" ); document.write( "Hope this helps.
