Question

please answer the question.....​

Answer 1

Answer:

a) 150m

Step-by-step explanation:

(Length of tree/ length of its shadow)= (length of pole/ length of its shadow)

=> 12/8= x/100

=> x= 150.

So length of flag pole is 150m.

Answer 2

Answer:

(a) 150m

Step-by-step explanation:

Let length of flag pole be 'x'm.

The tree is 12m tall and casts a shadow 8m long.

tanФ= 12/8

       = 3/2

At the same time, a flag pole casts a shadow 100m long. Since it's cast at the same time, this means that the two triangles are similar to each other.

$3/2 = x/100\\x = 300/2\\ = 150$

Therefore, the flag pole is 150m long.
