It they weren't equal is wouldn't make a tessellation.
A regular tessellation is one that uses regular polygons. An interior angle of a regular pentagon measures 108 degrees. A full circle, 360 degrees, is not divisible by 108 degrees. Consequently, it is not possible to arrange a number of polygons so that they meet at a point without gap or overlap.
135 Each interior angle of a regular octagon measures 135 degrees.
The sum of the interior angles is 360.
Exterior angle measures 18 degrees Interior angle measures 162 degrees
The polygon will have 12 equal sides and each interior angle measures 150 degrees.

Each interior angle of a regular heptagon measures 900/7 degrees.The interior angles of all polygons meeting at a point must sum to 360 degrees. But that would require 360 / (900/7) = 2.8 - that is you would require 2.8 regular heptagons to meet at each vertex. Since it is not possible to have a fraction of a heptagon. the tessellation required by the question is impossible.
The sum of the measures of the interior angles of a heptagon is 900 degrees.
find the sum of the measures of the interior angles of 13-gon.
135 Each interior angle of a regular octagon measures 135 degrees.
The sum of the interior angles is 360.
Exterior angle measures 18 degrees Interior angle measures 162 degrees
Each interior angles measures 150 degrees

180 degrees
If each interior angle measures 174 degrees then it will have 60 sides
Each interior angle measures 150 degrees Each exterior angle measures 30 degrees
