45 is my first choice answer
Answer:
15.9 centimeters
Step-by-step explanation:
the information we have is:
Perimeter: 
Number of sides of the polygon: 
since each side has equal length, we can use the following equation to find the measure of one side of the polygon, the equation for perimeter:

where n is the number of sides and
is the length of each side.
So we clear for
and we get:

and subtituting the known values:

each side is 15.6 centimeters long
Answer:
To figure out if 2 lines are parallel, compare their slopes. You can find the slope of a line by picking 2 points with XY coordinates, then put those coordinates into the formula Y2 minus Y1 divided by X2 minus X1. Calculate the slope of both lines. If they are the same, then the lines are parallel.
