12 exterior angles that add up to 360 degrees
12 interior angles that add up to 1800 degrees
Its interior angles add up to 1800 degrees
Exterior angles: 360 degrees Interior angles: 1620 degrees
90 x ((2 x 12) - 4) degrees ie 1800o
The interior angles of an 11-gon add up to 1620 degrees
A 9-gon is a polygon with nine sides and nine angles
The interior angles of a 12-gon add up to 1800 degees
12
Its interior angles add up to 1800 degrees
Measures of what? The interior angles, the exterior angles, the lengths of sides?
100
It has 18 interior angles.
1800 degrees
A 12-gon has 12 sides.
NONE
23 of them.
180x28 is the sum of the interior angles in a 30- gon
Not surprisingly, the answer is 20.
