Question

at a certain time a tree 6m High casts a shadow of length 8 metres at the same time a pole casts a shadow of length 20 m find the height of the pole

Answer 1

Hello!

Let the height of the pole be x.

Then,

6 : 8 = x : 20

⇒ 6 / 8 = x / 20

⇒ 8x = 20 × 6

⇒ 8x = 120

⇒ x = 120 / 8 ⇒ x = 15 m

Hence, Required height of the pole is 15 m

Cheers!

Answer 2

Answer:

Step-by-step explanation:-

Let the height of pole be x

Then, 6 : 8 : : x : 20

= 6/8 = x/20

= 8x = 20 × X

= 8x = 120

= x = 120 / 8

= X = 15
