Question

Find the angle sum of a convex polygon, with number of sides

(a) 12
(b) 10​

Answer 1

Case 1 :

Number of sides = 12

Angle Formula = ( n - 2 ) × 180

Here n is the number of sides

→ ( 12 - 2 ) × 180

→ 10 × 180

→ 1800°

Polygon with 12 sides has 1800° as sum of angles

Case 2 :

Number of sides = 10

Angle Formula = ( n - 2 ) × 180

Here n is the number of sides

→ ( 10 - 2 ) × 180

→ 8 × 180

→ 1440°

Polygon with 10 sides has 1440° as sum of angles

Answer 2

Answer:

a) (12-2) ×180

10×180

1800°
