Use the formula "total degrees= 180x(n-2), where n= number of sides of the figure. So, 8x180=1440 degrees, divided by 10 angles=144.

The final part of the above answer is only true if all the angles of the decagon are equal. But there is no justification for assuming that the angles are all equal. In fact, they can have any value in the range (0, 360) degrees with the only restriction being that they add up to 1440 degrees.

What is the formula to find the measure of each interior angle of a regular polygon?
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.
What is the interior and exterior angle for a regular decagon?
A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.
How do you find the angle of a decagon?
Find any straight side of the decagon. Move along it until it joins another side. That is where an angle is. An angle of a decagon can have any measure between 0 and 360 degrees (except 180 degrees).
A regular decagon is inscribed in a circle find the measure of each minor arc?
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.
How do you find the interior angle of a decagon?
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
Find the measure of an exterior angle of a regular decagon?
360/10 = 36 degrees
How do you find the measure of one interior angle?
Use a protractor
B Find the measure of each interior angle of a regular 20-gon?
Each interior angle measures 162 degrees.
Find the measure of one interior angle of a regular decagon?
Decagon is 10 sided figure. Internal angles of 10 sided figure is (2 x 10 - 4) right angles = 16 x 90 degrees, hence one angle is (16 x 90)/10 = 16 x 9 = 144 degrees

The measure of an exterior angle of a triangle is120 degrees the interior angles that are not adjacent to this exterior angle are congruent find the measure of the interior angles of the triangle?
They are all 60 degrees.
The measure of an interior angle of a regular polygon is 150 degrees Find the number of sides?
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
