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

        int a, b, c;
        double s, l, h;

        a = scanner.nextInt();
        b = scanner.nextInt();
        c = scanner.nextInt();

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