Answer:
The angle of elevation of the sun is 30°.
Among the given options option (b) 30° is correct.
Step-by-step explanation:
Given : The length of the shadow of a tower on the plane ground is √3 times the height of the tower.
Let the height of the tower is AB
The length of the shadow of a tower ,BC = √3 AB
Let angle of elevation of the Sun is θ .
In right angle ∆ ABC ,
tan θ = P/B
tan θ = AB/BC
tan θ = AB/√3AB
tan θ = 1/√3
tan θ = tan 30°
[tan 30° = 1/√3]
θ = 30°
