Question

7. The ratio of the length of a rod and its shadow is V3: 1. What is the angle of
elevation of the sun?​

Answer 1

Hence ,The angle of elevation of the sum is 30°.

Given :-

l(BC)

l(AB)

= 31

now, angle of elevation, ∠ACB=θ

now, tanθ=tan(∠ACB)=

BC

AB

= 31

⇒tan θ=( 31 )

=tanθ=(tan 6 )

⇒θ= 6π

∴ The angle of elevation = 6

π =30∘.

I send you image also and give you in written way also so which you understand better in that way u solve.
