The picture is black, is it just me?
1/16 would be your answer. I hope this helped!
The answer would be 142 degrees because for supplementary angles they needs to equal 180. So you take 180-38 and get 142

Answer: 10 feet</h3>
===================================================
How to get this answer:
A pentagon has 5 sides. If each side is the same length, then each side is 20/5 = 4 feet long. That halves to 4/2 = 2 feet. Each side is now 2 feet long, and there are 5 total sides, so 2*5 = 10 feet is the new perimeter.
A shortcut is to simply divide the perimeter in half to get 20/2 = 10. The reason why this works is because the perimeter is the sum of all the sides, which are all being cut in half.
-----
Algebraically, if we had the five sides a,b,c,d,e then
P = a+b+c+d+e
is the perimeter
Cutting each side in half gives
0.5*a+0.5*b+0.5*c+0.5*d+0.5*e = 0.5*(a+b+c+d+e) = 0.5*P
showing that we've cut the perimeter in half.
