Answer 1

Hi friend,

# 43.30m

➡Complete solution :-

Refer to this diagram ,

Let the the tower = AB

BC is original shadow

BD is final shadow

Given BD-BC = CD = 50m

Therefore , in ABC,
tan 60° = AB/BC
=> AB/root 3 = BC.....i)

➡Therefore, In ABD
tan 30° = AB/BD
Or, 1/root 3 = AB/(BC +CD)
Or , ABroot 3 = AB/root 3+50..(1)
Or, AB root 3 - AB root 3 = 50
Or, 3 AB-AB root 3 = 50
Or , AB = 50 root 3/2
= 25 root 3
= 25*1.732 = 43.30m

...i hope it helps you
