Question

Is there someone that is on here that will help me with my geometry because I'm not getting any of this, please?

Answer 1

A nonagon had nine sides and the interiors angles equal 1260 degrees. X is on of those interior angles. So 1260/9 equals 140.
X =140

Answer 2

The answer above is correct, however, if you are seeing more of these questions in the future and don't know how to do it. you take the amount of sides (9) - 2 to get 7. Then multiply by 180 to get 1260. 1260/9 is 140
