Answer:
The radius of each circle is 2.5 units
Step-by-step explanation:
If you replace the x with -4 and multiple that by 0.5 then minus that from 14 you will get -16
The formula for interior angle sum is 180(n - 2).
Backtrack it from that.
180(n - 2) = 1980.
1980 / 180 = 11 = n - 2.
11 + 2 = 13 = n.
The polygon has 13 sides.
