the angle of elevation of the tower from a point on the ground is 30 degree at a point on the horizontal line passing through the foot of the tower and 100m near it the angle of elevation is found to be 60 degree find the height of the tower and the distance of the first point from the lower

Step-by-step explanation:
tan 60°=h/100
so h=100*√3m ---------(1)
tan 30°=h/(100+x)-------(2)
so from (1) put value of h in equ (2)
we get that
tan 30°=100√3/(100+x)
100+x=100√3/tan30°
100+x=100√3*√3
100+x=100*3
x=200m
