Question

finite of vertical pole if the angle of elevation is 30° when it's top is
observed from a point 60 M away from its foot​

Answer 1

we know tan ... see pic

height p of the required pole....

P = 60/√3

= 20√3 ans

means

Answer 2

$\tan(30) = \frac{h}{60 } \\ \frac{1}{\sqrt{3} } = \frac{h}{60} \\ h = 20 \sqrt{3} m$
