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
To get the answer to this question simply add he numerators but keep the denominator the same which will give you 2/6 then you simplify the answer by 2/2 to get the simplified answer 1/3
-$12.99
That should be it, hit me up for any additional questions
