Question

the ratio of the length of a rod and its shadow is 1:1/root3 .what is the angle of elevation of the source of light

Answer 1

Here, AB = Length of rod
BC = Length of shadow.

So 1 : 1/✓3 = AB/BC
√3 = AB/BC

We know that AB/BC = tan theta

So, tan theta = √3
tan theta = tan 60°
theta = 60°

Hope This Helps You!

Answer 2

Hey there,

In the given figure, let's say----

AB=p=length of pole
BC=b=length of shadow

then tan C=AB/BC=p/b

Since p/b=1:1/√3=√3:1

This implies that tan C=√3

Angle of elevation of source of light=∠C

∠C=tan⁻¹√3

Therefore ∠C=60°
