Sum of central angles must be 360 deg whatever the number of sides so in this case, assuming polygon is regular, ie sides are equal, the answer is 360/12 = 30 degrees.
a 12 sided polygon!:) * * * * * Oh dear! A 12 sided polygon is a dodecagon, not a decagon. The correct answer is 10 sides.
If it is a regular polygon then it will have 360/12 equals 30 sides
Each interior angle in 12-sided polygon is 150 degrees.
If it is a regular 12 sided polygon then each interior angle is 150 degrees.
Degrees are used to measure angles, not the lengths of sides.
The sum of the interior angles of a 12 sided polygon add up to 1800 degrees.
Providing that it is a regular 12 sided polygon then each exterior angle measures 30 degrees
The interior angles of a 12 sided polygon add up to: (12-2)*180 = 1800 degrees
A 12 sided polygon is a dodecagon
The name of a 12 sided polygon is dodecagon.
A 10-sided polygon is a decagon. A 12-sided polygon is a dodecagon.
Each exterior angle of a regular 12-gon measures 30 degrees.
An 11 sided polygon is a hendecagon and a 12 sided polygon is a dodecagon
