Answer:
63.79 degrees to the nearest hundredth.
Step-by-step explanation:
Sum of the interior angles of a polygon = 180(n - 2) where n = the number of sides.
Sum in a heptagon = 180(7 - 2) = 900 degrees.
In a regular heptagon one interior angle = 900/7 = 128.57 degrees.
So 2x + 1 = 128.57
2x = 127.57
x = 63.79.
