Draw this:
\n" ); document.write( "Angle of 70 degrees has the ground distance the cosine of 70=x/4
\n" ); document.write( "x=4 cos 70=1.37 m
\n" ); document.write( "-
\n" ); document.write( "for angle of 80 degrees, the cosine to be less and x=4 cos 80=0.69 m
\n" ); document.write( "The range is (0.69 m, 1.37 m)
\n" ); document.write( " \n" ); document.write( "

\n" );
