Answer: 2748.5 feet
Step-by-step explanation:
Given that the
Height h = 120 feet.
angle of depression = 2.5 degrees
The angle of depression is equal to the angle of elevation.
The base of the observation deck will be achieved by using trigonometry ratio.
Tan Ø = opposite/ adjacent
Opposite = height = 120 feet
Adjacent = base = ?
Substitutes the given parameters into the trigonometry ratio.
Tan 2.5 = 120 / adjacent
Adjacent = 120 / tan 2.5
Adjacent = 2748.452
Therefore, the base of the observation deck is 2748.5 feet
8x = 44 -4
8x = 40
x = 40/8
x = 5
Its wrong for x = 2
y = (3/4) * 2^2 = 3 (NOT 4)
Answer:
what is the options
Step-by-step explanation:
To find the surface area of the rectangular prism the area of all the sides must be found and added together.
The formula for the surface area of a rectangular prism can be expressed as:

where

= length

= height

= width
Before plugging in the values in the equation the length of the prism must be converted to inches
1 ft. = 12 in.
Therefore 2 ft. = 24 in.
By plugging in the values of length, width, and height into the equation
2(24)(14) + 2(24)(11) + 2(14)(11) = 1508 in.²
