Question

Q7. The length of the shadow of a tower on the plane ground is v3
times the height of the tower. The angle of elevation of sun is:
(a) 45° (b) 30° 1760° (d) 30°​

Answer 1

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°  

Answer 2

Answer:30°
