### Question:
Position { static double angleBetweenPoints_YasKatethe(Disk firstPoint, Disk secondPoint) { double a = Math.abs(firstPoint.getPosition().y - secondPoint.getPosition().y); double b = Math.abs(firstPoint.getPosition().x - secondPoint.getPosition().x); double c = Math.sqrt(a * a + b * b); return Math.abs(Math.toDegrees(Math.asin(a / c))); } Position(double x, double y, double z);  public Double x; public Double y; public Double z; }### Answer:
@Test void angleBetweenPoints_YasKatetheTest() { double angle = Position.angleBetweenPoints_YasKatethe(disk1, disk2); assertEquals(44.99999999999999, angle); }
