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.
3x3x3x3 = 81
x.x.x.x = x^4
2x2x2x2 = 16
B. 81x^4/16
Answer:
Area of the fig. = 127 yards^2
Step-by-step explanation:
So,Seeing carefully we see 3 figures : 2 rectangles & 1 square,
So, first of all Area of the Big Rectangle
Area of the rectangle = l*b
length = 13 & breadth = 9
= 13*9
= 117 yards^2
Now, Area of the small rectangle
Length & Breadth = 3 & 2
Area = 3*2
= 6 yards^2
Area of one and only square in the fig.
= S*S (side = 2)
= 2*2
= 4 yards^2
Total area of whole fig. = (117 + 6 + 4) yards^2
= 127 yards^2
Hope it works!
Answer:
$7.40
Step-by-step explanation:
785 of 24 is 18.72, 150in = 4.17yrd, 4.117*5 is the minimum whole number that reaches 18.72, 5*1.48=7.40
