Problem: For given two sides of a triangle a and b and the angle C between them, calculate the following properties:

* S: Area of the triangle
* L: The length of the circumference of the triangle
* h: The height of the triangle with side a as a bottom edge



Input

The length of a, the length of b and the angle C are given in integers.

Output

Print S, L and h in a line respectively. The output should not contain an absolute error greater than 10-4.

Example

Input

4 3 90


Output

6.00000000
12.00000000
3.00000000

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws Exception {
        Scanner sc = new Scanner(System.in);

        double a =sc.nextDouble();
        double b =sc.nextDouble();
        double c =Math.toRadians(sc.nextDouble());

        System.out.println(a*b*Math.sin(c)/2);
        System.out.println((a+b)+(Math.sqrt((a*a)+(b*b)-2*a*b*Math.cos(c))));
        System.out.println(b * Math.sin(c));
    }
}
