tan 25=24000/y where y is the distance between a point on the ground below
\n" ); document.write( ":
\n" ); document.write( ": the plane and the airport---->24000=tan 25 (y)----->y=51,502ft\r
\n" ); document.write( "\n" ); document.write( ":
\n" ); document.write( "sin 25=24000/x where x is the distance between the plane and the airport
\n" ); document.write( ":
\n" ); document.write( ": 24000=sin 25(x)-----y=56,738ft
