n ( n − 2 ) ⋅ 180 ​ n = 7 7 ( 7 − 2 ) ⋅ 180 ​ = 7 5 ⋅ 180 ​ ≈ 128. 6 ∘

konrad509 · Answer

The measure of each interior angle of a heptagon is approximately 128.6 degrees. This is calculated using the formula for the interior angles of polygons. The calculation involves substituting the number of sides, which is 7 for a heptagon, into the formula.
