> LESSON 12 Polygons and Quadrilaterals Unit Test What is the measure of each interior angle of a regular, 12-sided polygon? (1 point) O 150° O 140° O 130 O 120° ( point​

Answer 1

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}}`
