Answer:
A. 
Step-by-step explanation:
Given:
The regular polygon is a decagon having 10 sides.
Perimeter of the given polygon is,
.
We know that, perimeter of a regular polygon of
sides is given as,
where,
is the length of each side.
Here, 
Plug in these values and solve for
. This gives,

Therefore, the side length of the given polygon is 
Answer:
126
Step-by-step explanation:
25-2=23
2+3=5
23-5=18
7*18=126
Answer:
0/16
Step-by-step explanation:
you use the equation y2-y1/x2-x1 so -12-(-12) which is 0 then do -18-(-2)=-16 so the slope is 0/-16
Amplitude: 1/4 (= |a|)
Frequency: 1/2 (= |b|)
Period: 4pi (= 2pi/|b|)
