x/45=40/5, similar triangles (draw this)
\n" ); document.write( "x=360 feet height of building, 8 times the length of its shadow.
\n" ); document.write( "-also
\n" ); document.write( "shadow is 9 times longer for the building, so height needs to be 9 times more than the flagpole, or 360 ft.
\n" ); document.write( "
\n" );
