Answer:
- 36° .
⠀
Explanation :
⠀
For a regular polygon of n sides, we have
[tex]\bf \longrightarrow \qquad Each \: exterior \: angle = { \bigg( {\dfrac{360}{n} } \bigg)}^{ \circ} [/tex]
⠀
Here, We are to find the measure of each exterior ange of a regular decagon.
⠀
- So, we know a regular decagon has 10 sides, so n = 10 .
⠀
Now, substituting the value :
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{360}{10} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle _{(Decagon)}= { \bigg( {\dfrac{36 \cancel0}{1 \cancel0} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{36}{1} } \bigg)}^{ \circ} [/tex]
⠀
[tex] \pmb{\bf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = 36^{ \circ} }[/tex]
⠀
Therefore,
- The measure of each exterior angle of a regular decagon is 36° .
Answer:
It is 36 degrees because the out side is equal to 360 degrees
If you divide that by ten you get 36 for each angle
