document.write( "Let x be the height of the pole, in meters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then  tan(60°) = \"x%2F5.4\" = \"sqrt%283%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence,  x = \"5.4%2Asqrt%283%29\" = 9.353074361 = 9.353 meters (rounded as requested).    ANSWER\r\n" );
