Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
150 degrees
Assuming the measure of the arc refers to the angle at the centre of the circle, the answer is 180 - 150 = 30 degrees.
150 degrees.
Feet measure length, square feet measure area. Your question has no answer.
150 degrees
150 degrees
150 degrees 1440-1290 = 150
The angles are: 150+30 = 180 degrees
The 12 angles add up to 1800 degrees and 1800/12 = 150 degrees
Each interior angles measures 150 degrees
Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
It is 150 degrees.

Assuming the measure of the arc refers to the angle at the centre of the circle, the answer is 180 - 150 = 30 degrees.
To find an exterior angle of a regular 12-gon, use the formula to find the total sum of all the angles first: total sum of all angles = (n-2)*180where 'n' is the number of sides, or 12.By solving, you will find that the total sum of all angles is 1800 degrees, so since it is a regular polygon, you can divide by 12 to find the measure of each interior angle, which is 150 degrees.Once you know the measure of the interior angles, since an exterior angle is the supplement of an interior angle, subtract 150 degrees from 180 degrees (the measure of a straight line) to find the exterior angles, which will be 30 degrees.
