Answer:
The height of the tree is 21 ft
Step-by-step explanation:
we know that
A light post that is 9 feet tall that casts a shadow that is 6 feet long
so
by proportion
Find out the the height of the tree if a tree that casts a shadow that is 14 feet long
Let
x ----> the height of the tree

therefore
The height of the tree is 21 ft
140 * .45 = 63
Add 140 and 63
2. 203 because you are adding 45% of 140 to increase it by 45%
Same with the other except subtraction
4. 15
I think this is right, I am not sure
To find the answer you need to subtract 180 - 25 to get your fianl answer which is 155!
