Solution:
The image of the question is attached below.
Ratio of the triangles is 1 : 1.
AC = 2x + 10 and EC = 4x − 18.
Since the two triangles ACB and DCE are in the ratio 1 : 1, so their corresponding sides are also in the ratio 1 : 1.
Therefore sides AC and EC are corresponding to each other.
AC : EC = 1 : 1
Subtract 10 from both sides of the equation.
Subtract 4x from both sides of the equation.
Divide by -2 on both sides, we get
⇒ x = 14
Distance between the top and bottom of the bridge is EA.
EA = AC + EC
= 2x + 10 + 4x - 18
= 6x - 8
= 6(14) - 8
= 84 - 8
EA = 76 feet
Distance between the top and bottom of the bridge is 76 feet.
Answer: 59.58 ft
Step-by-step explanation:
Given
The area of the neighbor's fence is
Suppose the length of the fence is L and the shape of the fenced area is square
So, we can write
According to the question, Cody's fence length must be twice of neighbor's
The length of Cody's fence is
I don't know if it's right but this is what I did. the rounding might be a little different.
