Answer:
x = 110°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Sum the given angles and equate to 720
125 + x + 130 + 90 + 165 + 100 = 720, that is
610 + x = 720 ( subtract 610 from both sides )
x = 110°
