A 5 m 60 cm high vertical pole casts a shadow 3 m 20 cm long. Find at the same time (i) the length of the shadow cast by another pole 10 m 50 cm high (ii) the height of a pole which casts a shadow 5m long.

Text Solution

Verified by Experts

Here the given solution:
(i) `(x_1)/(y_1)=(x_2)/(y_2)`
` ⇒ 5.6/3.2= 10.5/(y_2)`
`⇒y_2=6 cm`
(ii) `(x_1)/(y_1)=(x_3)/(y_3)`
`⇒ 5.6/3.2= (x_3)/5`
`⇒x_3=8.75m`
