![30^(\circ)](https://img.qammunity.org/2020/formulas/mathematics/high-school/g45d27fv58mtenk6bi8ebnmylcqt522qwc.png)
Explanation:
We are asked to find the measure of each exterior angle of a regular dodecagon.
We know that a regular dodecagon is a 12 sided regular polygon with each side equal.
We know that measure of each angle of n-sided regular polygon can be found using formula:
![\text{Each exterior angle}=(360^(\circ))/(n)](https://img.qammunity.org/2020/formulas/mathematics/high-school/j27du5jncdq3ul2soie4p48io86qbg46qv.png)
Upon substituting
in above formula, we will get:
![\text{Each exterior angle of a regular dodecagon}=(360^(\circ))/(12)](https://img.qammunity.org/2020/formulas/mathematics/high-school/n6dwvu2s7vrtsf9iuv6f1qp9lks5qg5p0h.png)
![\text{Each exterior angle of a regular dodecagon}=30^(\circ)](https://img.qammunity.org/2020/formulas/mathematics/high-school/gnaio0pvfk9zk2g3x17efq1k8lz62jl681.png)
Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.
