Geometry math question no guessing and show work you

We use angle sum property of triangle here :

sum of three angles = 180 degrees

118.6 + 42.3 + third angle =180

160.9 + third angle =180

third angle =180-160.9

third angle =19.1 degrees

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.

f is the midpoint of
