Answer:
Step-by-step explanation:
Regular polygons are those polygons whose sides are equal in length and whose angles are all equal.
By definition each interior angle of a Regular polygon is given by:
(In degrees)
Where "n" is the number of sides of the polygon.
In this case you know that the polygon shown in the picture is a Decagon, which means that it has 10 sides. Then:
Therefore, you must substitute that value of "n" into and then you must evaluate.
Through this procedure, you get that the measure of an interior angle of the Regular Decagon is:
