? = 73°
There are 7 sides in this polygon
Calculate total interior angles using (n-2) * 180
["n" denotes number of sides]
- Here total interior angle: (7-2)*180 = 900°
The missing angle inside the polygon:
900° - 130° -119° -130° -154° -130° -130°
900° - 793°
107°
A straight line has total 180°
? + 107° = 180°
? = 180° - 107°
? = 73°
