Answer:
Step-by-step explanation:
The given hexagon has interior angles
x,x,x, x/2, x/2, x/2 for a total of S1=4.5x.
We also know that the sum of interior angles of any polygon of n sides is
S2=180(n-2)
For a hexagon, S2 = 180(6-2) = 720°.
Equating S1 and S2
4.5x = 720
x = 720/4.5 = 160.
Therefore substitute x in the given angles to get
{160°,160°.160°,80°,80°,80°}
Step-by-step explanation:
Each piece is 20 inches long.
Step-by-step explanation:
The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces
Given
String length = 168 inches
Number of pieces = 6
So the length of each piece will be:

Cutting 8 inches from each piece means that the length will be reduced 8 inches

Hence,
Each piece is 20 inches long.
