Question

find the elevation of sun when 5m. pole cast a shadow of lenght of 5 m​

Answer 1

Answer:

Let the angle of elevation be

′

θ

′

.

In, △ACB,

⇒tanθ=

BC

AB

=

5

5

3

⇒tanθ=

3

⇒ Or θ=60

∘

Step-by-step explanation:

hence the angle will ne 60*

Answer 2

$\huge {\colorbox {black}{\color {lime}{༆ Solution ᭄}}}$

Here, let ABC be a ∆ in which AB is the side (5m long), CB is the shadow cast by the pole (5m long) and angle B is a right angle.

_______________________________________

So, height of pole/length of shadow cast

= AB/CB

= 1

_______________________________________

We know that,

tan 45° = 1

This implies that,

The angle of elevation of sun is 45°.
