The railroad mound has the cross section of a isosceles trapezoid. The lengths
of the bases are \(12\, \mathrm{m}\)
and \(8\, \mathrm{m}\), the
height is \(3\, \mathrm{m}\).
Find the angle at the leg and round to the nearest degrees and minutes. See the picture with a isosceles trapezoid.
\(56^{\circ }19'\)
\(41^{\circ }45'\)
\(48^{\circ }11'\)
\(33^{\circ }69'\)
