For a decagon, it would be 1440°. They are not the same thing as polygons which are star domains. It is considered irregular because the angles and sides are not equal.

This question cannot be answered because the shape is not a regular polygon.

90° + 60° + 30° = 180°. A regular decagon has all sides of equal length and each internal angle will always be equal to 144°. 90° + 60° + 30° = 180°. Every regular polygon with n sides can be divided into n congruent triangles.

Since the interior angle of a regular pentagon at each corner is 108°, the corresponding polygon must be a star polygon with its edges subtending that.

How can i find $k$ in the function $a(x) = kx^2$ when said function describes the area of a star formed by a regular pentagons segments which the sides of the equilateral decagon each measure $x.$ i am extremely confused by this problem, and the teacher did not provide a diagram to go with it.

So a decagon has 10 angles.

They are denoted by p/q, where p is the number of vertices of the convex regular polygon and q is the jump between vertices.
