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:
B
Step-by-step explanation:
When you look at the model, you see that the bottom of the shape is square. So looking at the flat model, which one is thhe one with a square as a base. B does.
Answer:
X =50 Y is also 50 since they are vertical angles
Step-by-step explanation:
70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )
130 +X =180
X = 180-130
X=50
Answer:
the range is 20
Step-by-step explanation:
so here is how you find the range here is an example
the range data is 42 , 28 , 41, and 22
you first order the range data from least to greatest which is 22 , 28 , 41 , 42
after you order the numbers you want to get the largest number from the data and subtract it from the smallest number in the data which is 42 - 22 = 20
20 is the range
i hope this helps. i had this question on my test today and got a 100%
