I need to find the fifth side. I have a polgon(5 sided).
The distnace:
A to B= 4"
B to C =8"
C to D = 18"
D to E = 23"
E to A = ? in which is 39"

How do I find E to A if it is applied?

The numbers changing in polygon, sometime A to B is missing so I have to find the value for 8"

question: if I have four sided how can I predict the fifth sides?

I know it is very difficult to answer but what are the limitations in which the answer for the above is 39 for A to E.
