Question

a 5cm stick casts a shadow of 2 cm on the ground find the length of the shadow of 170 m tall tower of the same time​

Answer 1

Answer:

Step-by-step explanation:

Height of the pole H1, = 5 m

Length of the shadow of the pole, X1 = 2 m

Height of the tower = H2 m

Length of the shadow of the tower, X2 = 170 m

Since, if the two shadows cast, that will form two triangles which will be similar. Therefore, the ratio of their corresponding sides will be equal.

Therefore.

H1/H2 = X1/X2

5/H2 = 2/170

H2 = 425

Hence the height of the tower is 425m

Answer 2

Answer:

Height of the stick = 5 cm

Length of the stick's shadow = 2 cm

Heigh of the tower = 170 m

Length of the shadow of the tower = x

Since if two shadows will cast, that will form two triangles which will be similar. Therefore, the ratio of their corresponding side will be equal.

First we have to make 170 m to cm. So that, it will match to the height of stick.

1m = 100 cm

170 m = 170 x 100

So, 17000

⭐HS/HT = LS/LT

⭐5/17000 = 2/60

85000 = 30

Now reduce there no. by doing the lowest form..

You'll get your answer.
