18. Find the height of the mountain

A girl was flying in a parachute. She observes the top of the mountain at an angle of elevation of 45\(^{\circ}\) and the bottom of the mountain at an angle of depression of 60\(^{\circ}\). If a line is drawn straight beneath the parachute, the distance from the point to the mountain is 967 \(m\), then the height of the mountain is 9672641.8441674.844967 \(m\).

 

(Note: Use \(\sqrt{3} = 1.732\))
