Answer:

so this is my answer 1-4(A) only number 5 is not finished! (a only)

a.

1.)1080°

sum of interior angle=

(n-2) (180°)

1080° =(n-2) (180)

n-2=6

n= 8 sides

2.)1260°

sum of the interior angle=

(n-2) (180) = 1200

=n-2 = 1260° ÷ 180°

=n-2 = 7

=n = 2 + 7

n = 9sides

3.)1620°

sum of the interior angle

=180°(n-2) = 1620°

=180°n -360 = 1620°

=180° =1980

= 11 sides

4.)1980°

sum of interior angles

=(n-2) • 180° = 1980°

=(n-2) • 180° = 1980°

—————— ———

180° 80

n-2 = 11

n = 13 sides
