Match the following. 1 . center of a regular polygon the common center of its inscribed and circumscribed circles 2 . central angle of a regular polygon the distance from the center of the polygon to a vertex 3 . radius of a regular polygon the perpendicular distance from the center of the polygon to a side 4 . apothem of a regular polygon an angle whose vertex is the center of the polygon and whose sides contain consecutive vertices of the polygon

A regular polygon is a polygon in which all the sides are equal.

This is the matched list.

1 . A center of a regular polygon is the common center of its inscribed and circumscribed circles

2 . The radius of a regular polygon is the distance from the center of the polygon to a vertex.

3.An apothem of a regular polygon is the perpendicular distance from the center of the polygon to a side.

4. A central angle of a regular polygon is an angle whose vertex is the center of the polygon and whose sides contain consecutive vertices of the polygon.

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6

-2x-4
