The longest mounted ladder used by the Dallas Fire Department is 108 ft long. The optimum operating angle of this ladder is 60 degrees. The ladder is mounted on the back of the 8 ft long truck.\r

\n" ); document.write( "\n" ); document.write( "B. How far away from the building would the ladder be placed?\r
\n" ); document.write( "\n" ); document.write( "ladder length =108\r
\n" ); document.write( "\n" ); document.write( "optimum angle = 60 deg.\r
\n" ); document.write( "\n" ); document.write( "vertical height = 108* cos 60\r
\n" ); document.write( "\n" ); document.write( "= 108*0.866\r
