Answer:
Step-by-step explanation:
exterior angle = 360/23 = 15 15/23
Inetrior angle = 180- 15 15/23 =
[tex]=180-15\frac{15}{23}\\\\=180-\frac{360}{23}\\\\=\frac{180*23}{23}-\frac{360}{23}\\\\ =\frac{4140-360}{23}\\\\=\frac{3780}{23}\\\\=164\frac{8}{23}[/tex]
Always sum of all exterior angle of any regular polygon is 360
Inetrior angle and exterior angle are linear pair
