Answer:
The answer to your question is: 111°
Step-by-step explanation:
The sum of the interior angles of a polygon is (n - 2) 180°
This polygon has 7 sides
Then n = 7
Process
120 + 158 + 126 + 125 + 121 + 139 + x = (7 - 2)180
120 + 158 + 126 + 125 + 121 + 139 + x = 5(180)
789 + x = 900
x = 900 -789
x = 111°
