If the height of a pole is 2√3 metres and the length of its shadow is 2 metres, find the angle of elevation of the sun ?
A. 70°
B. 80°
C. 60°
D. 50°Let AB be the pole and AC be its shadow. Let angle of elevation, ∠ACB = θ. Then, AB = 2√3m, AC = 2 m. tan θ = AB/AC = 2√3/2 = √3 θ = 60°. So,the angle of elevation is 60°
Top of a 15 metre high tower makes an angle of elevation of 60° with the bottom of an electric pole and angle of elevation of 30° with the top of the pole. What is the height of the electric pole?
A. 10 metres
B. 12 metres
C. 5 metres
D. 8 metresAngle of elevation of a ladder leaning against a wall is 60° and the foot of the ladder is 4.6 m away from the wall. The length of the ladder is : ____ ?
A. 9.2 m
B. 7.8 m
C. 2.3 m
D. 4.6 mFrom a point P on a level ground, the angle of elevation of the top of a tower is 30°. If the tower is 100 m high, the distance of point P from the foot of the tower is : ______ ?
A. 200 m
B. 173 m
C. 149 m
D. 156 mDetailed Solution The distance between P from foot of tower is PB. ⇒ PB = 173 m (approx). ∴ The distance between P from foot of tower is 173 m.
Angle of elevation of the sun, when the length of the shadow of a tree is √3 times the height of the tree, is : _____ ?
A. 60°
B. 90°
C. 30°
D. 45°Let AB be the tree and AC be its shadow.
Let ∠ACB = θ.
Then, AC/AB = √3
Cot θ = √3
θ = 30°
