> 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:

Answer is 150°

Step-by-step explanation:

» Interior angle sum of a polygon:

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

» Interior angle sum of a dodegon:

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

» Measure for each angle:

${ \tt{ = \frac{interior \: angle \: sum}{n} }} \\ \\{ \tt{ = \frac{1800}{12} }} \\ \\ = { \tt{150 \degree}}$
