Step-by-step explanation:
Sum of interior angles of a polygon
180°(n−2)
When n=10,
Sum of interior angles of a polygon
180°(n−2)
=180°(10−2)
=1440°
Therefore, Each interior angle of a regular heptagon measures 1440/10=144°
Sum of interior angles of a polygon
180°(n−2)
When n=7,
Sum of interior angles of a polygon
180°(n−2)
=180°(7−2)
=900°
Therefore, Each interior angle of a regular heptagon measures 900/7=128.6°
