Answer 1

Answer:

1)sum of interior angles in a Nonagon =1260°

2)Sum of exterior angles in a Nonagon

=360°

Step-by-step explanation:

Given:-

A regular polygon has 9 sides .

To find:-

Find

1)sum of interior angles

2)sum of exterior angles

Solution:-

Number of sides in a polygon=(n)=9

1)The sum of all interior angles in a n-sided polygon=(n-2)×180°

=>(9-2)×180°

=>7×180°

=>1260°

sum of interior angles=1260°

2)The sum of all exterior angles in a polygon =360°

Answer:-

1)sum of interior angles in a Nonagon=1260°

2)Sum of exterior angles in a Nonagon=360°
