Question

The angle of elevation of the top of the town tower is 60 degree and the horizontal distance from the observed as to the foot of the tower is hundred metre then the height of the tower will be

Answer 1

Answer:

let the height of tower be x

Explanation:

we can use

$\tan( \alpha ) = \frac{opposite \: side}{adjacent \: side} \\ \tan( 60) = \frac{x}{100} \\ \sqrt{3} = \frac{x}{100} \\ x = 100 \sqrt{3} \\ x = 100 \times 1.73 \\ x = 173m$
