Question

Find the sum of the interior angles of a 12-sided polygon.

1,080°
1,800°
2,100°
2,160°

Answer 1

The sum of the interior angles of a 12-sided polygon (dodecagon) can be found using the formula (n - 2) x 180°, where 'n' is the number of sides. For a 12-sided polygon, the sum is 1800°.

Step-by-step explanation:

To find the sum of the interior angles of a 12-sided polygon, we can use the following formula:

Sum of Interior Angles = (n - 2) × 180°

Where 'n' is the number of sides of the polygon. For a 12-sided polygon (also known as a dodecagon):

Sum of Interior Angles = (12 - 2) × 180° = 10 × 180° = 1800°

Therefore, the sum of the interior angles of a 12-sided polygon is 1800 degrees.

Answer 2

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180

So, (12-2) x 180 = 1800

Answer: 1800
