The height of flagpole is 12.5 feet.
Step-by-step explanation:
Given,
Height of woman = 5 foot
Shadow of woman = 6 feet
Ratio of height to shadow = 5:6
Shadow of flagpole = 15 foot
Height of flagpole = x
Ratio of height to shadow = x:15
Using proportion;
Ratio of height to shadow :: Ratio of height to shadow
![5:6::x:15\\](https://tex.z-dn.net/?f=5%3A6%3A%3Ax%3A15%5C%5C)
Product of mean = Product of extreme
![6*x=15*5\\6x=75](https://tex.z-dn.net/?f=6%2Ax%3D15%2A5%5C%5C6x%3D75)
Dividing both sides by 6
![\frac{6x}{6}=\frac{75}{6}\\x=12.5](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%3D%5Cfrac%7B75%7D%7B6%7D%5C%5Cx%3D12.5)
