A string running from the ground to the top of a fence has an angle of elevation of 45°. The string is 10 feet long. What is the
distance between the fence and where the string is pegged to the ground?
1 answer:
Answer: The distance between the fence and where the string is pegged to the ground is 7.07 feet.
Step-by-step explanation:
Since we have given that
Length of string = 10 feet
Angle of elevation = 45°
We need to find the distance between the fence and where the string is pegged to the ground.
We will apply "Cosine formula "
Hence, the distance between the fence and where the string is pegged to the ground is 7.07 feet.

Answer:
A
Step-by-step explanation:
Answer:
width: 7.5
length: 22.5
Step-by-step explanation:
width: x
length: 3x
Perimeter = 2L + 2W
60 = 2(3x) + 2x
60 = 6x + 2x
60 = 8x
x = 7.5
width: x = 7.5
length: 3x = 3(7.5) = 22.5

<em>AB</em> + <em>ACB</em> = <em>A</em> (<em>B</em> + <em>CB</em>) = <em>A</em> (<em>I</em> + <em>C </em>) <em>B</em>
Taking the inverse gives
(<em>A</em> (<em>I</em> + <em>C </em>) <em>B</em>)⁻¹ = <em>B </em>⁻¹ (<em>I</em> + <em>C</em> )⁻¹ <em>A</em> ⁻¹
so the answer is (A)
Answer:
Stephen has 9 trees
Alice has 21 trees
Step-by-step explanation:
<u>At the beginning:</u>
Stephen = x trees
Alice = x + 12 trees
<u>At the end:</u>
Alice = (x + 12) - 4 trees
Stephen = x + 10 trees
Total = 36
Then
Stephen - 9 trees
Alice - 9 + 12 = 21 trees
