From a point on a bridge across a river, the angles of depression of the banks on opposite sides of the river are \(30^°\) and \(45^°\), respectively. If the bridge is at a height of \(3 m\) from the banks, find the width of the river.
Width of the river is
\(2 (1 + \sqrt{3} ) m\)
\(3 (1 + \sqrt{3} ) m\)
\(2 (1 + \sqrt{2} ) m\)
\(3 (1 + \sqrt{2} ) m\)
