Answer:
The tree is 28 feet tall.
Step-by-step explanation:
It is given that:
Height of flag pole = 8 feet
Shadow of flag pole = 6 feet
Ratio of height to shadow = 8 : 6
Shadow of nearby tree = 21 feet
Height of nearby tree = x
Ratio of height to shadow = x : 21
8 : 6 :: x : 21
Product of means = Product of extremes
6x = 8*21
6x = 168
Dividing both sides by 6
Therefore,
The tree is 28 feet tall.
i'm going to assume you're supposed to solve for x
Answer:
x = -2
Step-by-step explanation:
so you're trying to get x out of the equation and by it self
i would start this off by setting the equation equal to 0
then subtract 6
i would then divide by 3 on each side
you should then have x+4=2
you then subtract 4 to cancel it out
you then get your answer of x = -2
