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) {
    Scanner sc = new Scanner(System.in);

    int a = sc.nextInt();
    int b = sc.nextInt();
    double C = Math.toRadians(sc.nextInt());
    double c = Math.sqrt((a*a) + (b*b) - 2 * a * b * Math.cos(C));

    double L = a + b + c;
    double h = b * Math.sin(C);
    double S = a * h / 2;

    System.out.format("%f\n%f\n%f\n", S, L, h);
  }
}
