The sum of the interior angle measure of a 13-sided polygon is 1980 degrees.
It is solved by doing:
180(s-2)
180(13-2)
180(11)
= 1980 degrees
*s- meaning sides*
Providing that it is a regular polygon then each interior angle will measure 160 degrees
Providing that it is a regular 38 sided polygon then each interior angle will measure: 170o31'34.74''
51º per interior angle
How many sides does a regular polygon have if the measure of each interior angle is equal to 172 degress ?
If the interior angle is 120° then the external angle is 180 - 120 = 60° Number of sides = 360 ÷ 60 = 6. The polygon is a Hexagon.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
Each interior angle will measure 156 degrees
Each interior angle will measure 162 degrees
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing that it is a regular polygon then each interior angle will measure 160 degrees
Im stuck on that too :/
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
A 16 sided polygon
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
