5/3 = x/21
3x = 105
x = 35 feet
3x = 105
x = 35 feet
Let's assume that the height of the flagpole is "x" feet.
According to the information provided, the woman's height is 5 feet, and her shadow is 3 feet long. The length of the flagpole's shadow is 21 feet.
Now, we can set up a proportion:
(Length of woman's shadow) / (Woman's height) = (Length of flagpole's shadow) / (Flagpole's height)
Using the given values, we have:
3 / 5 = 21 / x
To solve for x, we can cross-multiply:
3x = 21 * 5
3x = 105
Now, divide both sides of the equation by 3 to solve for x:
x = 105 / 3
x = 35
Therefore, the height of the flagpole is 35 feet.
Let's call the height of the flagpole "x".
According to the given information, the woman's height is 5 feet and her shadow length is 3 feet. The flagpole's shadow length is 21 feet.
We can set up a proportion:
Height of the woman / Length of the woman's shadow = Height of the flagpole / Length of the flagpole's shadow
5 feet / 3 feet = x / 21 feet
Cross-multiplying, we get:
5 feet * 21 feet = 3 feet * x
105 feet = 3 feet * x
Now, we can solve for x by dividing both sides of the equation by 3 feet:
105 feet / 3 feet = x
Simplifying:
35 = x
Therefore, the height of the flagpole is 35 feet.
