Answer 2

Given :- The length of the shadow of a pole 12 meters high is 9 meters on the ground .

To Find :- At the same time the length of the shadow of the pole 18 meters high will be ?

Answer :-

Let us assume that, the shadow and pole makes an angle θ in the ground .

so,

→ tan θ = Height of pole / length of shadow

→ tan θ = 9 / 12

→ tan θ = 3/4 .

now, at the same time value of θ will be same .

then,

→ tan θ = Height of another pole / length of shadow of another pole .

→ 3/4 = 18 / shadow

→ 3 * shadow = 18 * 4

→ shadow = 6 * 4

→ shadow = 24 cm. (Ans.)

Hence, at the same time the length of the shadow of the

the length of the shadow of thepole 18 meters high will be 24 cm.
