Answer: The answer is 381.85 feet.
Step-by-step explanation: Given that a window is 20 feet above the ground. From there, the angle of elevation to the top of a building across the street is 78°, and the angle of depression to the base of the same building is 15°. We are to calculate the height of the building across the street.
This situation is framed very nicely in the attached figure, where
BG = 20 feet, ∠AWB = 78°, ∠WAB = WBG = 15° and AH = height of the bulding across the street = ?
From the right-angled triangle WGB, we have

and from the right-angled triangle WAB, we have'

Therefore, AH = AB + BH = h + GB = 361.85+20 = 381.85 feet.
Thus, the height of the building across the street is 381.85 feet.
Answer:
x=2
Step-by-step explanation:

Add 14 to both sides

Square root it
x=2
The formula is : A=6a^2
So lets say its a cube with edge lengths of 4
We first find out the area of each side by multiplying 4*4
They you multiple the answer of that, 16, by 6, for each of the sides.
A = 96 Units ^2
