How do u solve this ???

28°

Step-by-step explanation:

Subtract 152° from 180° becuase a straight line angle is 180°

This leaves you with 180-152 = 28

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.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
