To approach the runway, a small plane must begin a 9 degggree descent starting from a height of 1125 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach? \r

\n" ); document.write( "\n" ); document.write( "--------------------------
\n" ); document.write( "sin(theta) = opposite/hypotenuse
\n" ); document.write( "Your Problem:
\n" ); document.write( "sin(9 degrees) = 1125/x
\n" ); document.write( "x = 1125/sin(9 degrees)
\n" ); document.write( "x = 7191.51 ft.
