Question

The length of the shadow lf a pillar is under root
$\sqrt{3}$
3 times its height .find the angle of elevation of the source of light​

Answer 1

60 degreeS is the angle of elevation.

Answer 2

let the height of the pillar be x.
therefore, the base will be of the measurement√3x.


now, tanA=x/√3x
=>tanA=1/√3
=>tanA=tan30°[since tan 30°=1/√3]
=>A=30°


therefore the angle of elevation of the light source is 30°.
