The vertical cross-section of the embankment around the pond has the shape of an isosceles trapezium. Calculate the angle of inclination of the embankment if the embankment is \( 2\,\mathrm{m} \) high, the top width is \( 3\,\mathrm{m} \) and the arms are \( 4\,\mathrm{m} \) long.
\( 30^{\circ} \)
\( 60^{\circ} \)
\( 26.57^{\circ} \)
\( 45^{\circ} \)
