Option C:
interior angle 144°, exterior angle 36°
Solution:
The given image is a regular decagon.
Therefore the number of sides (n) = 10
Each interior angle = [tex]\frac{(n-2) \cdot 180}{n}[/tex]
[tex]$=\frac{(10-2) \cdot 180}{10}[/tex]
[tex]$=\frac{8\cdot 180}{10}[/tex]
Each interior angle = 144°
Each exterior angle = [tex]\frac{360^{\circ}}{n}[/tex]
[tex]$=\frac{360^{\circ}}{10}[/tex]
Each exterior angle = 36°
Hence interior angle 144°, exterior angle 36°.
Option C is the correct answer.
