An interior angle of a heptagon can have any value in the range (0, 360) degrees - other than 180 degrees.
The only way to do it is to measure the angles, There is no formula that will give you the measure of an interior angle of any shape unless it happens to be regular. And there is nothing in the question to suggest that the shape might be regular.
It will have 10 equal sides
An exterior angle of a regular polygon and its corresponding interior angle = 180° If an exterior angle is 1/8 of the interior angle (A) then A + A/8 = 180 : 9A = 1440 : A = 160 Each exterior angle is thus 180 -160 = 20° The number of sides = 360 ÷ exterior angle = 360 ÷ 20 = 18
A regular polygon has sides of equal length, as well as interior angles of equal measure. But for any regular polygon, the sum of the measures of the exterior angles is 360 degrees. You can use this information to find out the measure of an interior angle, because the sum of the measures of each interior/exterior pair of angles is always 180 degrees. So to find the answer to this problem, divide 360 by 7. Each exterior angle is about 51.4 degrees. Subtract that number from 180. Each interior angle is about 128.6 degrees.
Each interior angle of the regular 8 sided octagon measures 135 degrees
Each interior angle measures 162 degrees.

Each interior angle: 140 degrees Each exterior angle: 40 degrees

360/number of sides and deduct the quotient from 180 which will give the measure of each interior angle
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
that's geometry so the formula to find the measure of each interior angle of a regular polygon is: Ia=stands for internal angle Ia=(n-2)180 ---------- n that's the formula.
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.
You use the fact that the sum of the interior angles of a regular polygon with n sides is:180(n-2) degreesNow you have the sum of measures of all the interior angles so divide that by n and you have the measure of each interior angle.
Its interior angles are: (10-2)*180 = 1440 degrees If its a regular 10 sided polygon then each interior angle is: 1440/10 = 144 degrees
