The point A(4, –1) is reflected over the x-axis. Use a mapping to find the coordinates of A’. A’(4, –1) A’(–4, –1) A’(4, 1) A’(–4, 1)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

any of them that add up to 180 degrees.
