Answer:

Step-by-step explanation:
Simplify both of the fractions so
to get 0.93 and
to get 0.57.
Then you put them back into fraction form.

Sum of internal angles of any polygon is: (n-2)x180
So measure of an interior edge is ( ( n - 2 ) x 180 ) / n = 140
So 140n = 180n - 360
40n = 360
n = 9
So it's a nonagon.
Hope this helps :)
