Answer:
the polygon has 10 sides
Step-by-step explanation:
Recall that the sum of the interior angles of a polygon of N sides is given by the formula:
Sum = (N - 2) * 180
and that the sum of the exterior angles of any polygon is always 360 degrees.
Since we are told that the sum of the interior angles is 4 times the sum of the exterior angles, we set the following equation:
(N - 2) * 180 = 4 * 360
Solving for N, we start by dividing both sides by 180:
(N- 2) = 4 * 360 / 180
N - 2 =4 * 2
N - 2 = 8
N = 10
So the polygon has 10 sides

Step-by-step explanation:
x² + y² − 8x + 10y − 8 = 0
Rearrange:
x² − 8x + y² + 10y = 8
To complete the square, take half of the x and y coefficients, square it, then add the result to both sides.
(-8/2)² = 16
(10/2)² = 25
x² − 8x + 16 + y² + 10y + 25 = 8 + 16 + 25
x² − 8x + 16 + y² + 10y + 25 = 49
Factor the squares:
(x − 4)² + (y + 5)² = 49
The center is (4, -5) and the radius is 7.
