This makes no sense because the rows have to be smaller than the bookshelf the rows fit in the bookshelf
the way to do it would be height of bookshelf/height per row=number of rows (round down) if we used that, then 112/316=0.35 rows round down 0 so we got 0 shelves because it is impossible to have a row higher than the bookshelf that it is on
it's d because if 74 would be the same as the left side next to x and if you turn that into a problem like 180-74 and I got 180 cause half of a circle is 180 and then my answer would be 106 I'm not good at explaining but it's d
