Answer:
101°
Explanation:
The given shape is a heptagon.
The sum its interior angles is calculated with the following formula:
(s-2)×180
- n is the number of sides.
(7-2)×180 = 900
- Now add all sides to find the value of x.
139 + 121 + 125 + 126 + 158 + 120 + x = 900
789 + x = 900
- Subtract 789 from both sides.
x = 101°
