Question 105721
The formula of measure of the interior angle of a polygon is:
{{{180(n-2)}}} where n is the number of sides of the polygon.
Since a pentagon has 5 sides, we substitute 5 for n.
{{{180(5 - 2)}}}
{{{180(3)}}}
{{{540}}}
THus, the measure of the interior angles of a pentagon ( take note, any kind of pentagon, not only for regular ones) is 540 degrees.

THank you.
