1. find the measure of one interior angle of a polygon with 12 sides.

2. find the measure of one interior angle of a polygon with 8 sides.

1) 150°  2)

Step-by-step explanation:

The total interior angle of a 12 sided polygon is = (12 - 2) 180° = 1800°.

1800° ÷ 12 sides=150°

The total interior angle of a 8 sided polygon is =(8-2) 180° = 1080°

1080 °÷ 8 sides= 135°
