the diagram shows a regular decagon please help

Answer:
36°
Step-by-step explanation:
[tex]size \: of \: one \: exterior \: angle \\ \\ = \frac{360 \degree}{no \: of \: sides} \\ \\ = \frac{360 \degree}{10} \\ \\ = 36 \degree[/tex]
Answer:
Exterior Angle = 36 degrees
Step-by-step explanation:
The measure of each interior angle of the decagon is 144
So,
Exterior Angle = 180 - 144 (Interior and Exterior angles are angles on a straight line hence adding up to 180 degrees)
Exterior Angle = 36 degrees
