From a point A on a level ground, the angle of elevation of the top tower is 30º. If the tower is 100 m high, the distance of point A from the foot of the tower is:

Answer is 173 m sin30 = 100 / hyp side

hyp side = 200 Now for distance of point A from the foot of the tower =cos30 * hyp side = 0.866 * 200 = 173 m

Distance from A to bottom of tower=P Height of tower =100m Angle of elevation from point A=30° Therefore Tan 30°=100/P P=100/tan30° =100/(1/√3) =173 So ans is 173m
