<u>Answer:</u>
The length of the person’s shadow is 5.7ft
<u>Explanation:</u>
Length of the flagpole =a= 35ft
Length of the shadow of the flagpole= b=50ft
Length of the person=c= 4ft
Suppose the length of the person’s shadow is=d
According to the rules of trigonometry
![\frac{\text { Length of the flagpole }}{\text { Length of the shadow of the flagpole }}=\frac{\text { Length of the person }}{\text { Length of the person's shadow }}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%20%7B%20Length%20of%20the%20flagpole%20%7D%7D%7B%5Ctext%20%7B%20Length%20of%20the%20shadow%20of%20the%20flagpole%20%7D%7D%3D%5Cfrac%7B%5Ctext%20%7B%20Length%20of%20the%20person%20%7D%7D%7B%5Ctext%20%7B%20Length%20of%20the%20person%27s%20shadow%20%7D%7D)
![\frac{a}{b}=\frac{c}{d}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%3D%5Cfrac%7Bc%7D%7Bd%7D)
![\frac{35}{50}=\frac{4}{d}](https://tex.z-dn.net/?f=%5Cfrac%7B35%7D%7B50%7D%3D%5Cfrac%7B4%7D%7Bd%7D)
35d=200
d=![\frac{200}{35}](https://tex.z-dn.net/?f=%5Cfrac%7B200%7D%7B35%7D)
d=5.7ft
Hence, The length of the person’s shadow is 5.7ft.
