8th grade math, please help.

The x = 102

Step-by-step explanation:

The whole angle is 180 so you have to do 180-78 to get the other angle .

x = 102

Step-by-step explanation:

x + 78 = 180 {linear Pair}

      x = 180 - 78

     x = 102

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.

step- i d k and i d c : )

you: : 0
