The value of AB in the given figure is
20 m
10 m
40 m
5 m
If AB = 4 m and AC = 8 m, the angle of elevation of A as observed from C is
60o
30o
45o
Cannot be determine
The ratio of height of a tower and the length of its shadow on the ground is √3 : 1. Then the angle of elevation
90o
If the angle of depression of an object from a 75 m height tower is 30o. Then the distance of the object from the base of the tower is
30√3 m
50√3 m
75√3 m
150 m
In Δ ABC, ∠ B = 90o, sin A = 1/2. If B = 6 cm, then AC =
6 cm
9 cm
12 cm
15 cm
A tower 100 √3 m high cause a shadow of 100 m from its foot, the angle of elevation is
0o
If the height and length of the shadow of a man are the same, then the angle of elevation of the sun is
15o
The angle formed by the line of sight with the horizontal, when the point being viewed is above the horizontal level is called
Vertical angle
Angle of depression
Angle of elevation
Obtuse angle
The measure of angle elevation of the top of a 75√3 m high tower from a point at a distance of 75 m from the foot of tower in a horizontal place is:
145o
A ladder of 10 m length touches a wall at a height of 5m. The angle θ made by it with the horizontal is
40o
