A funicular carries passengers up an embankment to an observation point. If the length of the track is 67.8 meters and the angle of inclination is \( 39^{\circ} 4^{\prime} \), determine the height of the embankment. The embankment is \( \square \) meters high. (Round to two decimal places as needed.)

4. Solve \( \sin 2 x=\cos x-\cos 2 x \) algebraically. Give your answer as a general solution, in degrees.
