Divide the shape into two parts, square triangle, the square is easy 2x2=4. The second part you know the length is 2 as 4-2=2, and because it is half of a square, it will be half of the area, so total answer is 6
The difference between 90% and 72% is 18%
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:
n-3
Step-by-step explanation:
Notice that the output is always 3 less than the input
output is input -3
f(n) = n-3
