tree which casts a shadow of 14 metres
under similar conditions.




plz ans it fast​

Answer 1

Step-by-step explanation:

given,

height of electric pole = 15m

length of its shadow = 10.5m

now,

let the height of tree be x metres

also the length of tree given is 14 metres

here, similar conditions means about sun that is casting the shadow ( both tree and pole are casting shadow with equal angles formed by cone)

therefore,

15/10.5 = x/14( draw triangles and use similarity

criterion)

now solve by cross multiplication and find the value of x that will be the height of the tree.

hope you like my explanation. I have told every detail, THANK YOU!
