we know that the heptagon has 7 sides
so on substituting n as 7 in the formula
we get =(n-2) 180=900° as the sum of all the angles in the heptagon.
Now,
we know that in a regular polygon all the angles are equal.
so measure of each angle = 900/7 = 128.5° {approx }
it is 128.5 degrees .

jamre: how
MrJ109: (n-2)pi is the the formula for sum of all angles in a polygon where n= number of sides
MrJ109: in heptagon it is 5 pi
jamre: smart and thanks for your answer
MrJ109: so each angle = (5 *180)/7 =128,5. pi =180 °
MrJ109: s2u friend
jamre: thx
MrJ109: if you like it please help me by marking it as brainliest answer. .....
MrJ109: I would be very grateful to you

The formula to find the sum of the interior angles of a polygon is
(n - 2)180

where n is the number of the sides in the polygon.


substitute this in this in the formula.
(7 - 2)180
5 \times 180
900degrees.


each angle is
 \frac{900}{7}
128.6 app.


the answer is 128.6 degrees.
