6/13 = x/30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6*30 = 13x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "180 = 13x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "180/13 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 180/13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 13.846\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the tree is roughly 13.846 ft high.\r
