Pentagon = 5 sides.
For regular pentagon: 360/5 = 72
180 - 72 = 108 degrees at each interior angle.
For non-regular pentagons, each interior angle may differ but the sum of the interior angles will be the same as a regular pentagon = 5 x 108 = 540 degrees.
If you mean a regular 9 sided nonagon Total interior angles are (9-2)*180 = 1260 degrees Each interior angle is 1260/9 = 140 degrees
156 degrees Sum of interior angles of a polygon=180(n-2), where n is the number of sides. To find one interior angle's measure, divide by the total number of angles, which is also the total number of sides.
Hexagon has 6 sides so 360/6 = 60 degrees interior angle therefore exterior angle = 360 - 60 = 300 degrees
the formula for the total of all the angle measures is (n-2)(180) n meaning the number of sides so then you do this- (5-2)180=130+94+109+112+x 3(180)=445+x 540=445+x 95=x
If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.
It is: 360/5 = 72 degrees for each exterior angle and each interior angle will be 108 degrees
The measure of an exterior angle of an equiangular pentagon is 72 degrees. An equiangular pentagon is a regular pentagon that has five equal sides and five equal angles. An interior angle of a pentagon is equal to 108 degrees.
72 degrees
Use a protractor
Each interior angle measures 162 degrees.

Subtract the interior angle from 180
They are all 60 degrees.
There are 540 interior degrees in a pentagon So: 540-112-102-118-107 = an angle of 101 degrees
AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
