Answer 2

x = 111

Explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 7

sum = 180° × 5 = 900°

Sum the given angles in the polygon and equate to 900

125 + 126 + 158 + 120 + x + 139 + 121 = 900

789 + x = 900 ( subtract 789 from both sides )

x = 111
