Answer:
m∠C = 108°
Step-by-step explanation:
The sum of the interior angles of a pentagon is 540°. Divide this sum by the number of angles to find the degrees of each one:
540/5 = 108

Step-by-step explanation:
You are incorrect.
We are going from ABCDEFGH to A'B'C'D'E'F'G'H'. We are going from the large octagon to the small octagon. The scale factor of a dilation is the number you multiply the original lengths to get the lengths of the dilation.
![scale~factor = \dfrac{length~of~dimension~in~dilated~image}{length~of~corresponding~dimension~in~original~figure}](https://tex.z-dn.net/?f=scale~factor%20%3D%20%5Cdfrac%7Blength~of~dimension~in~dilated~image%7D%7Blength~of~corresponding~dimension~in~original~figure%7D)
Look at point (6, 0) which becomes (3, 0) in the dilation.
The distance from the origin to (6, 0) is 6 units.
The distance from the origin to (3, 0) is 3 units.
scale factor = dilated/original = 3/6 = 1/2
The scale factor of the dilation is 1/2.
Also look at segment AB whose length is 4. The length of segment A'B' is 2.
scale factor = dilated/original = 2/4 = 1/2
Answer: 1/2
