SOLUTION
Let us use a simple diagram to interprete the question
In the diagram above, the dark stuff below represents the shadow and the rectangular bar represents the building. I have labelled the height of the building as h.
So we will use the right-angled triangle formed to find h
As we can see h represents the opposite side and 56.5 feet represents the adjacent side of the right-angle triangle. So we will use TOA

So we have

Hence the answer is 104.9 feet to the nearest tenth
Answer:
x = y - 2 / 2
Step-by-step explanation:
y = 2x + 2
2x + 2 = y
2x = y - 2
x = y - 2 / 2
They give you: <RSP = 90 degrees
If you look in the diagram, <RSP is vertical to <UPW and vertical angles have the same measure. <RSP = <UPW
So the correct answer is A.
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
2y + 8 = 2 • (y + 4)
Equation at the end of step 2 :
(0 - (4 • (4y - 10))) + 6 • (y + 4)
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
4y - 10 = 2 • (2y - 5)
Equation at the end of step 4 :
(0 - 8 • (2y - 5)) + 6 • (y + 4)
Step 5 :
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
64 - 10y = -2 • (5y - 32)
Final result :
-2 • (5y - 32)
(-6,26) are the coordinates of the other endpoint because it it the same distance from the midpoint in the opposite direction of the other endpoint
