Solve for x. Sin x =3/8

<x=22.02431284 degrees

Step-by-step explanation:

sin(x)=3/8

sin^-1(3/8)=<x

<x=22.02431284 degrees

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.
