Answer the following questions based on the given information.
The Surya Kiran is an aerobatics demonstration team of the Indian Air Force, and was formed in 1996. In Surya Kiran demonstrations, fighter pilots perform aerobatic maneuvers in groups of 3, to entertain an audience.
Anuja and Sarthak are watching planes A, B and C at a Surya Kiran demonstration in Jaipur. Anuja is watching the demonstration from the Hawa Mahal, while Sarthak is at the City Palace. Both of them are 1365 m apart, as shown in the figure below.

(Note: Treat the airplanes and people as point-sized objects. The figure is not to scale.)
i) When the angle of elevation of plane B from Anuja's eyes is 30°, the plane's altitude is 675 m above ground.
What is its horizontal distance from where Anuja is standing? Draw the figure and show your steps.
ii) When the planes are in landing formation, the pilot from plane B can see plane A at an angle of elevation of 30°. Plane B is 740 m above ground level, and the horizontal distance between plane A and plane B is `50 sqrt 3` m.
What is the altitude of plane A? Draw the figure and show your steps.
iii) The angle of elevation of plane C from Sarthak's eyes is 60°, while its angle of elevation from Anuja's eyes is 45°.
What is the plane's horizontal distance from Sarthak? Draw the rough figure and show your steps.
OR
During a maneuver, the pilot from plane A can see Anuja at an angle of depression of 60°, and Sarthak at an angle of depression of 30 degrees.
What is the altitude of the plane? Draw the figure and show your steps.
