The coordinates of a point are in reference to the origin, the point with coordinates (0,0). The existence (or otherwise) of an angle are irrelevant.
180-interior angle = exterior angle 360/exterior angle = number of sides

The only way to do it is to measure the angles, There is no formula that will give you the measure of an interior angle of any shape unless it happens to be regular. And there is nothing in the question to suggest that the shape might be regular.
The idea is to calculate the average of the x-coordinates (this will be the x-coordinate of the answer), and the average of the y-coordinates (this will be the y-coordinate of the answer).
Divide the sum by 180 and add two to that number. That will give you n.
180-interior angle = exterior angle 360/exterior angle = number of sides
Divide the number of sides into 360 which will give you the exterior angle and subtract this angle from 180 which will give you the interior angle.
360/number of sides and deduct the quotient from 180 which will give the measure of each interior angle
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
coordinates
Well this is my thought depending on where the point of dilation is the coordinates of the give plane is determined. The point of dilation not only is main factor that positions the coordinates, but the scale factor has a huge impact on the placement of the coordinates.
The minimum interior angles of a polygon add up to 180 degrees which would give each interior angle of an equilateral triangle 60 degrees
Divide the number of sides into 360 degrees and then subtract your answer from 180 degrees to give you the interior angle. For example a regular hexagon has 6 equal sides and 360 divided by 6 = 60 degrees (the exterior angle) 180 - 60 = 120 degrees (the interior angle)
It is: (number of sides -2)*180 = sum of interior angles If its a regular polygon then: sum of interior angles/number of sides = each interior angle

-- If they give you one set of 'x' and 'y' coordinates, then you have the location ofone point on the line. One point doesn't have a slope.-- If they give you two sets of 'x' and 'y' coordinates, then you have the locations oftwo points on the line. The slope of the straight line between two points is(the difference between the 'y' values) divided by (the difference between the 'x' values)
