Question

The angle of elevation of the top of a tower at a point on the level ground is 30 degree after walking a distance of 100 m towards the foot of the tower along the horizontal line through the foot of the tower on the same level ground the angle of elevation of the top of the tower is 60 degree find the height of the tower

Answer 1

distance between angle 60 and height of tower is 50 so by using tan60=
$\sqrt{3}$
therefore height of tower is
$50 \times \sqrt{3}$
