Question

A vertical pole is 12m high and the length of its shadow is 12√3m . what is the angle of elevation of the sun

Answer 1

Step-by-step explanation:

let angle of elevation be " theta."

in the figure, AB is the pole of 12m and BC is its shadow of (12 root 3)m.

we know that ,

tan theta = P/H

$\frac{12}{12 \sqrt{3} }$

$= \frac{1}{ \sqrt{3} }$

and tan 30 = 1/ root 3

so angle of elevation is 30 degree. ans
