For a regular polygon having 10 sides, the interior angle between the sides of the polygon, in degrees, is

The correct answer is 144.

To find the interior angle of a regular polygon, we can use the formula for the measure of each interior angle of a regular polygon with $n$ sides:

$\text{Interior Angle}=\frac{(n-2)\times 180°}{n}$

Here, the polygon has 10 sides, so we substitute $n=10$ into the formula:

$\text{Interior Angle}=\frac{(10-2)\times 180°}{10}$

First, subtract 2 from 10:

$10-2=8$

Next, multiply by 180°:

$8\times 180°=1440°$

Finally, divide by the number of sides (10):

$\text{Interior Angle}=\frac{1440°}{10}=144°$

Thus, the interior angle between the sides of a regular 10-sided polygon is 144 degrees.
