Answer:
3362 ft²
Step-by-step explanation:
As we saw in brainly.com/question/22284853, the long side of the area will be half the length of the fence: 82 feet. The remaining two sides will be 41 feet each, so the largest area that can be enclosed is ...
A = LW
A = (82 ft)(41 ft) = 3362 ft²
Answer:
422.44 feet
Step-by-step explanation:
Let A, B, X, and H represent the left-most observation point, the observation point to its right, the point immediately below the apex, and the height of the apex, respectively.
Then the definition of the cotangent function tells us ...
AX = H·cot(42°)
BX = H·cot(48.85°)
Since the figure tells us AB = 100 feet, we have ...
AB = AX -BX
100 = H·cot(42°) -H·cot(48.85°)
H = 100/(cot(42°) - cot(48.85°)) ≈ 422.44 . . . . ft
The current height of the pyramid is 422.44 feet.
Answer:
See explanation below
Step-by-step explanation:
If x is even, then we know that x = 2k for a k ≥1
If y is odd, then we know that y = 2j -1 for a j≥1
Therefore, x + y can be written similarly as:
And clearly, 2(k + j) -1 is odd.
Therefore, the sum x + y is an odd number.
