Calculate 51degree 29munites+32degree 46munites

51° 29' + 32° 46' = (51+32)° (29+46)'

= 83° 75' . . . . . there are 60' in 1°, so 75' = 1° + 15'

= 84° 15'

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.
