1,440°

Step-by-step explanation:

We know that to find the angle sum of any polygon we use the formula

• (n - 2) × 180[where n is the number of sides]

So, To find the angle sum of a 20 sided polygon

We can use

• (n - 2 ) × 180
• (20 - 2 )× 180
• 18 × 180
• 3240°

We can use the same formula to find the angle sum of a 12 sided polygon

• (n - 2) × 180
• (12- 2) × 180
• 10 × 180
• 1800°

Now in the question we are asked to find How much more is the sum of the angle of a 20 sided polygon than a 12 sided polygon.

So, We can just subtract the angle sum of 12 sided polygon from 20 sided polygon.

=>3240 - 1800

= 1,440°
