Answer 2

Step-by-step explanation:

from the above table,we observe that

sum of the angles = (n-2) ×180°

where n = no. of sides.

a.)No. of sides = n=7

sum of angles = (n-2) × 180°

=(7-2)×180°

=5×180°

=900°

b.)No. of sides = n=7

sum of angles = (n-2) × 180°

=(8-2)×180°

=6×180°

=1080°

c.)No. of sides = n=7

sum of angles = (n-2) × 180°

=(10-2)×180°

=8×180°

=1440°

d.)No. of sides = n=n

sum of angles = (n-2) × 180°
