Question

Find the sum of angles of a 12 sided polygon ?​

Answer 1

Answer:

The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees. The internal angle at each vertex of an regular dodecagon is equal to = = 150 degrees. ... The total exterior angle of a 12 sided polygon is 360 degrees.

Hope it helps you.

Answer 2

Given:

There are 12 sides of a polygon.

To Find:

The angle sum of a polygon with number of sides 12.

Solution:

We know that,

If a polygon has n sides, then its interior angle sum is given by the following equation:

S = ( n −2) × 180°

Here, we have n = 12

So, by substituting n = 12 in the equation, we get

S = ( 12 −2) × 180° = 10 × 180° = 1800°

Hence, the angle sum of a  polygon with the number of sides 12 is 1800°.
