Answer:
Step-by-step explanation:
To find the angles of any shape with all sides equal in length, we use the formula:
, where n is the number of sides
For a pentagon, we get the equation:


Thus the measure of each in a pentagon if the lengths of all five sides are equal is 108 degrees.
Hope that helps!
I believe it would be1/25 or 2/13 but im not quite sure
What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:
78:13:65
It also depends on what your teacher is asking of you.
