Question

calculate the sum of the angle of a polygon with:
(i).10 sides (ii).12 sides
(iii).20 sides
​

Answer 1

Step-by-step explanation:

Sum of the angles of a 10 Sided polygon=10-2X180=1440

Answer 2

Answer:

Formula for sum of angles of a polygon = ( n-2) 180 (Where n is the number of sides)

Sum of angles of a polygon with 10 sides = (10-2) 180

= 8×180

=1440

12 sides

= (12-2) 180

= 10 × 180

=1800

20 sides =

=(20-2) ×180

= 18 × 180

= 3240
