Question

What is the angle of elevation of the Sun when the length of the shadow of a vetical pole is equal to its height?

Answer 1

Answer:

45°

Step-by-step explanation:

Tan b = height/base = 1

so b = 45

Answer 2

Answer:

The angle of elevation of the Sun is 45°.  

Step-by-step explanation:

Given : The length of the shadow of a vertical pole is equal to its height .  

Let height of a vertical pole, AB = h & length of its shadow , BC = h

Let angle of elevation of the Sun is θ .

In right angle ∆ ABC ,  

tan θ = P/B  

tan θ  = AB/BC

tan θ  = h/h

tan θ  = 1

tan θ  = tan 45°  

[tan 45° = 1]

θ = 45°  

Hence, the angle of elevation of the Sun is 45°.
