HELP ME! Thank you sooo much!! Will report if you post a link or something random. Find the sum (this is a pre-calculus question). Normally the sum would be 50, but this is a pre-calculus question and you have to solve it differently instead of just combining the numbers.

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.
