What is the sum of the interior angle measures of a polygon that has 20 sides
1 answer:
Answer:
The answer is 3,240
Step-by-step explanation:
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.
In mathematics, the interior angles of a polygon are the angles on the inside of the polygon created where the sides of the polygon meet. When a polygon is a n-sided regular polygon, meaning it has n sides, its sides have the same length, and its angles have the same measure, we have that the measure of one interior angle is given by the formula

The answer is:
The x-coordinate of the solution to the system of equations is:
We can solve the problem writing both equations as a system of equations.
So, we are given the equations:
Then, solving by reduction we have:
Multiplying the first equation by 2 in order to reduce the variable "x", we have:
Now, substituting "y" into the first equation, to isolate "x" we have:
Hence we have that the x-coordinate of the solution to the system of equations is
