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
Hexagon has 6 sides so 360/6 = 60 degrees interior angle therefore exterior angle = 360 - 60 = 300 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.
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.
A pentagon has a total interior angle sum of 540 degrees. Since a pentagon has five sides, you can find the measure of each interior angle by dividing the total angle sum by the number of sides, resulting in an average interior angle of 108 degrees.
It is: 360/5 = 72 degrees for each exterior angle and each interior angle will be 108 degrees
To find the measure of each interior angle of a regular pentagon, first calculate the sum of the interior angles using the formula ( S = 180(n-2) ). For a pentagon, ( n = 5 ), so ( S = 180(5-2) = 180 \times 3 = 540 ) degrees. Since a regular pentagon has equal interior angles, divide the sum by the number of angles: ( \frac{540}{5} = 108 ) degrees. Therefore, each interior angle of a regular pentagon measures 108 degrees.
72 degrees
Use a protractor
To find the measure of an exterior angle of a triangle, you can use the property that the exterior angle is equal to the sum of the two opposite interior angles. First, identify the exterior angle you want to measure, and then add the measures of the two non-adjacent interior angles. Alternatively, if you know the measure of one interior angle, you can subtract it from 180 degrees to find the exterior angle at that vertex.
Each interior angle measures 162 degrees.

Subtract the interior angle from 180
There are 540 interior degrees in a pentagon So: 540-112-102-118-107 = an angle of 101 degrees
They are all 60 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
