Solve for b. 11 3 b b = [?] Pythagorean Theorem: a2 + b2 = c2 Enter. ​

√112

Step-by-step explanation:

a^2+b^2=c^2

3^2+b^2=11^2

9+b^2=121

b^2=121-9

b^2=112

b=√112

Mark me as brainliest

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.
