22. Determine the altitude of the helicopter

A passenger in the helicopter spots a ship and a blue whale at an angle of 30\(^{\circ}\) and 45\(^{\circ}\), respectively. If the ship is exactly behind the whale, then the distance between them is 138 \(m\), then the altitude of the helicopter above the sea level is 188.52189.52190.52187.52 \(m\). (Use \(\sqrt{3} = 1.732\))
