Write a program to get the angles of a triangle by using the given points. Round the resultant angles to the nearest integer value.

Input (Point, Point, Point) Output (Angles)
`[0, 0], [5, 0], [0, 5]` `45.0, 90.0, 45.0`
`[90, 0], [0, 0], [45, 77.94]` `60.0, 60.0, 60.0`
`[0, 2], [5, 0], [0, 5]` `45.0, 112.0, 23.0`
`[0, 0], [10, 0], [5, 7.666]` `66.0, 57.0, 57.0`
`[25, 43], [50, 0], [50, 43]` `90.0, 60.0, 30.0`

``` class CalculateThreeAngles {    public static void main(String s[])    {        Point firstPoint = new Point(0, 0);        Point secondPoint = new Point(5, 0);        Point thirdPoint = new Point(0, 5);        System.out.println("Angles of the triangle are : " + getAngles(firstPoint, secondPoint, thirdPoint));    } public static Angles getAngles(Point firstPoint, Point secondPoint, Point thirdPoint) { //Write code here to get the angles of a triangle. } //If required write any additional methods here } class Point { double x; double y; Point(double x, double y) { this.x = x; this.y = y; } } class Angles { double angleA; double angleB; double angleC; public Angles(double angleA, double angleB, double angleC) { this.angleA = angleA; this.angleB = angleB; this.angleC = angleC; } @Override public String toString() { return (angleA + ", " + angleB + ", " + angleC); } } ```
