Answer» Here, AB = Length of rodBC = Length of shadow. So 1 : √3 = AB/BCq/√3 = AB/BC We know that AB/BC = tan theta So, tan theta = 1/√3tan theta = tan 30°theta = 30°

Answer»

Here, AB = Length of rodBC = Length of shadow.

So 1 : √3 = AB/BCq/√3 = AB/BC

We know that AB/BC = tan theta

So, tan theta = 1/√3tan theta = tan 30°theta = 30°
