Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:

Putting the values, we get,

Thus, there are 10 sides. The regular polygon is a regular decagon.
All you do is subtract 3.2 from the number 4 and you get the number -0.8
