Doubling the side length multiplies the area by 4
Not sure what the y coordinates in this question are so I’m just using generic placeholders.
The midpoint between the points (-9, A) and (4, B) is the point (-5/2, (A+B)/2).
P = 2*(L + W) = 2*(51.125 +38.25)
P = 178.75 . . . ft . . . . . selection A
For the tan of angle X use opposite/adjacent. So, 36/27 =4/3.
Answer: Hexagon AGHBGHCGHDGHEGHFGH coincides with hexagon ABCDEF when GH passes through themidpoints of opposite sides; that is, it is a perpendicular bisector of the two sides. HexagonAGHBGHCGHDGHEGHFGH also coincides with hexagon ABCDEF when the line of reflection joins a pair ofvertices opposite one another on the hexagon. There are three perpendicular bisectors and three pairs ofopposite vertices. In all, there are six lines of reflection that will map the hexagon back onto itself.
