Answer:21 m
Step-by-step explanation:
Given
A flag pole and its shadow form the sides of a right triangle
Hypotenuse=35 m
Shadow length=28 m
As the Triangle is right angle therefore we can apply Pythagoras theorem.
Let pole length be x
[tex]x^2+(28)^2 =(35)^2[/tex]
[tex]x^2=1225-784=441 m[/tex]
[tex]x=\sqrt{441}=21 m[/tex]
