Answer:
There are 7 teams in the league
Step-by-step explanation:
Given that the number of games is given by:

The equation will be used to determine the number of games. As we already know, that 21 games are scheduled which means G(n) is 21 so we have to find n when G(n) is 21
Putting this mathematically

Multiplying equation by 2

As the number of teams cannot be negative, the number of teams in league are 7.
Hence,
There are 7 teams in the league
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:
