It is a triangle.
The formula for the total of interior angles in an n-sided polygon is 180(n-2).
This is 180 degrees for triangles, 360 degrees for quadrilaterals, and 540 degrees for pentagons.

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 6840 degrees
If each interior angle is 176 degrees it will have 90 equal sides.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 3240 degrees
To answer this question it has to be assumed that it is a regular polygon ie with equal angles. Sum of the interior angles = (7-2)*180 = 5*180 = 900 degrees So each interior angle = 900/7 = 128.57 degrees.
The total of the interior angles equal 5040, and each angle measures 168 degrees The total of the exterior angles equal 360, and each angle measures 12 degrees
