Find the measure of each interior angle of a regular polygon of ^@10^@ sides.
Answer:
^@ 144 ^ \circ ^@
- We know that the sum of all exterior angles of a polygon is ^@360 ^ \circ.^@
- Each exterior angle of a regular polygon of ^@10^@ sides ^@= { \Bigg ( \dfrac{ 360 } { 10 } \Bigg ) } ^ \circ = 36 ^ \circ.^@
- Thus, each interior angle of a regular polygon of ^@10^@ sides ^@ = 180 ^ \circ - 36 ^ \circ = 144 ^ \circ ^@.
