ABCD is a square plot . The angle of elevation of the top of a pole standing at D from A and C is `30^@` and that from B is `theta`, then `tantheta` is equal to

ABCD is a square plot.The angle of elevation of the top of a pole standing at D from A and C is 30^(@) and that from B is theta, then tan theta is equal to

ABCD is a square plot. If the angle of elevation of the top of the pole standing at D from A or C is 30^(@) and that from B is theta , then cot theta-sqrt(6) is

An observer who is 1.62m tall is 45m away from a pole . The angle of elevation of the top of the pole from his eyes is 30^(@) . The height ( in m ) of the pole is closest to :

A person observed that the angle of elevation at the top of a pole of height 5 metre is 30^(@) . Then the distance of the person from the pole is :

Consider a regular hexagon ABCDEF. Two towers are situated at B and C. The angle of elevation from A to the top of the tower at B is 30^(@) , and the angle of elevation to the top of the tower at C is 45^(@) . What is the ratio of the height of towers at B and C ?
