Question

A vertical stick 1.2m long casts shadow 40cm long on the ground. At the same time a pole 6m high casts a shadow x on the ground. The value of x is

Answer 1

Answer:

In △ABC and △DEF

∠A=∠D=90∘

Since the tower and the stick cast their respective shadows at the same time on the ground,

So, ∠C=∠F

∴△ABC∼△DEF      ....(by AA similarity)

DEAB=DFAC⇒x12=408

⇒x=60 m
