In the X direction,
\n" ); document.write( " $\"X=160cos%28195%29%2B610cos%28104%29=-154.5-147.6=-302.1\"$
\n" ); document.write( "In the Y direction,
\n" ); document.write( " $\"Y=160sin%28195%29%2B610sin%28104%29=-41.4%2B591.9=550.5\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"D=sqrt%28%28-302.1%29%5E2%2B%28550.5%29%5E2%29\"$
\n" ); document.write( "Work that out for the distance in km. \n" ); document.write( "
