Angle of Elevation and Depression

A man from the top of a 100 metres high tower sees a car moving towards the tower at an angle of depression of 30^@ . After some time, the angle of depression becomes 60^@ .The distance (in metres) travelled by the car during this time is

A man from the top of a 100 m high tower sees a car moving towards the tower at an angle of depression 30°. After some time, the angle of depression becomes 60°. What is the distance travelled by the car during this time ?

A man from the top of 100 metres high tower sees a car moving towords the tower at an angle of depression of 30^(@) . After some time the angle of depression becomes 60^(@) . The distance travelled by the car during this time is _____ metres

The angle of depression of a point on the ground from the top of a tree is 60^(@) . Lowering down 20 m from the top, the angle of depression changes to 30^(@) . Find the distance between the point and the foot of the tree. Also find the height of the tree.
