Answer:
[tex]129^{\circ}[/tex]
Step-by-step explanation:
n = Number of sides of a polygon = 7
The interior angles of a polygon is given by
[tex]\theta=\dfrac{(n-2)180^{\circ}}{n}[/tex]
[tex]\Rightarrow \theta=\dfrac{(7-2)\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{5\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{900^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=128.57^{\circ}\approx 129^{\circ}[/tex]
Each interior angle of a heptagonal nut is [tex]129^{\circ}[/tex].
