On a horizontal plane there is a vertical tower with a flag pole on the top of the tower. At a point 9 metres away from the foot of the tower the angle of elevation of the top and bottom of the flag pole are `60^0a n d30^0` respectively. Find the height of the tower and the flag pole mounted on it.

Explanation

In `DeltaACD`

`tan60^o=(AC)/(DC)`

​=`sqrt(3)​=(AC)/9`
​
=`AC=9sqrt(3)
​m`

In `DeltaDBC`

`tan30^0=(BC​)/(DC)`

=`1/sqrt(3)=(BC)/9`
