### Question:
TurtleSoup { public static double calculateRegularPolygonAngle(int sides) { throw new RuntimeException("implement me!"); }  static void drawSquare(Turtle turtle, int sideLength); static double calculateRegularPolygonAngle(int sides); static int calculatePolygonSidesFromAngle(double angle); static void drawRegularPolygon(Turtle turtle, int sides, int sideLength); static double calculateBearingToPoint(double currentBearing, int currentX, int currentY,
                                                 int targetX, int targetY); static List<Double> calculateBearings(List<Integer> xCoords, List<Integer> yCoords); static Set<Point> convexHull(Set<Point> points); static void drawPersonalArt(Turtle turtle); static void main(String args[]);  }### Answer:
@Test public void calculateRegularPolygonAngleTest() { assertEquals(60.0, TurtleSoup.calculateRegularPolygonAngle(3), 0.001); assertEquals(128.57, TurtleSoup.calculateRegularPolygonAngle(7), 0.01); assertEquals(108.0, TurtleSoup.calculateRegularPolygonAngle(5), 0.001); }
