Solve for θ if cosθ = 0.81. Round answer to the nearest degree.

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.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

the answer is y = 11.54

hope this : )
