Answer:

Answer is 150°

Explanation:

» Interior angle sum of a polygon:


= { \tt{180(n - 2)}}

» Interior angle sum of a dodegon:


= { \tt{180(12 - 2)}} \\ = { \tt{180 * 10}} \\ = { \boxed{ \tt{1800 \degree}}}

» Measure for each angle:


{ \tt{ = (interior \: angle \: sum)/(n) }} \\ \\{ \tt{ = (1800)/(12) }} \\ \\ = { \tt{150 \degree}}
