we know that 52-gon means a polygon having 52 sides. There is a formula for calculating the sum of interior angles of a polygon : (2n-4) x 90° or (n-2) x 180° , where 'n' = number of sides.
Now, for sum of the interior angles of 52-gon: (n-2) x 180° =(52-2) x 180° =50 x 180° =9000°
the answer is the sum of the measures of the interior angles of a 52-gon is 9000°
