A \(3\, \mathrm{m}\) long
rod is in a slant position with respect to the observer's eye: one end is in the distance
\(20\, \mathrm{m}\) and the
other one \(18\, \mathrm{m}\).
Find the visual angle of the rod (the angle between the lines which connect the
observer's eye and the ends of the rod) and round to the nearest degrees.
