What is the measure of DAC?

- 30
- 45
- 60
- Not enough information

I would say not enough information.

Step-by-step explanation:

because you cant calculate the angle DAC unless you have at least 1 or two of the angles.

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.
