Answer:
The formula that calculates the sum of the interior angles of a regular polygon is equal to : (n-2)180° ; n represents the number of sides of the polygon.
So now, we've to replace n by 35 in the formula :
(35-2)180°
And by carrying out the calculation, we obtain: 5940°.
Therefore, the sum of all the interior angles of a regular 35-sided polygon is 5940°.
