Question

2. When the length of the shadow of a pole or height
"m is equal to 1 m then find the clovation or the
Source of light​

Answer 1

Answer:

Let AB=h be the height of the pole.

The shadow of a pole will form base BC

Let θ be the angle of elevation.

According to the fig.

tanθ=

BC

AB

⟹tanθ=

h

h

=1

⟹θ=tan

−1

(1)

⟹θ=45

o

Hence, the angle elevation is 45
