Find the difference. 60° 50' 40" - 30° 40' 50"

It should be 60

By my understanding

It might be 40° 0' 30"

or 30° 60' 30"

I think that the first one is correct

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.

hope this !

let me know
