Question

Math Grade 8

Answer 1

The angles of a regular pentagon add up to 180°. So, you can set up this equation:
$5x = 360$

And then solve for x:
$x = \frac{360}{5} = 72$

So, the interior angle is equal to 72°.

Answer 2

72 degrees
Since it's a regular polygon with 5 sides, you divide 360 by 5. You'd end up with 72. Hope this helps
