A ladder of 10 m length touches a wall at a height of 5m. The angle θ made by it with the horizontal is
90o
60o
40o
30o
If a pole 10 m high cause a shadow 10 m long on the ground, then the sun's elevation is
45o
When the angle of elevation of the sun is 30o, the length of the shadow caused by 15 m high building is
50/√3 m
50√3 m
25√3 m
100√3 m
A ladder of 10m length touches a wall at a high of 5m. The angle θ made by it with the horizontal is
The length of the string of a kite flying at 100 m above the ground with the elevation of 60o is
100 m
100√2 m
200/√3 m
200 m
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
The ratio of height of a tower and the length of its shadow on the ground is √3 : 1. Then the angle of elevation
The length of shadow of a tower 50 m high at the time of the angle elevation 45o is
50 m
75 m
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
If AB = 4 m and AC = 8 m, the angle of elevation of A as observed from C is
