30o
The figure shows the observation of point C from point A. The angle of depression of point C from A is.
75o
The ratio of height of a tower and the length of its shadow on the ground is √3 : 1. Then the angle of elevation of sun is
If a pole 10 m high cause a shadow 10m long on the ground, then the sun's elevation is.
If a pole of height of 6 m cause a shadow 2√3 m long on the ground. Then the sun's elevation is.
