If you make a diagram, and construct a triangle, the 11° angle of descent equals the 11° in the triangle...we would use the tangent relationship...
\n" ); document.write( "Let the distance we want to be x.
\n" ); document.write( "Then tan 11° = 9500/x and
\n" ); document.write( "x = 9500/tan 11°
\n" ); document.write( "x = 48873 m or about 49000 meters (about 30 miles!)
\n" ); document.write( "
\n" );
