An electric pole, 14 metres high, casts a shadow of 10 metres. Find the height of a tree that casts a shadow of 15 metres under similar conditions.

As shadow is directly propotional to height, we can say that,

Height/Shadow =k, where k is a constant.

So, in case of electric pole,

1410=k→(1)

In case of tree,

HT15=k→(2), where HT is height of tree

So, from (1) and (2),

1410=HT15

HT=14∗1510=21m

So, height of tree is 21 meters.

hope it helps thank yo

i think c. but don't trust it.

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
