If you mean angles of 127, 152, 112, 123, 135, and 105 then 900 minus 754 = 146 degrees which is the remaining angle because the interior angles of a 7 sided heptagon add up to 900 degrees
It is 146 degrees.
Any angle that you like.
it's a heptagon
An interior angle of a convex heptagon can have any value in the range (0, 180) degrees.
Each interior angle is approximately 128.57 * * * * * That is only true of a REGULAR heptagon. The question does not state that it is regular.
It is 146 degrees.
