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 final int BIG_NUM  = 2000000000;
	public static final int MOD  = 1000000007;

	public static void main(String[] args) {

		Scanner scanner = new Scanner(System.in);
		double a = scanner.nextDouble();
		double b = scanner.nextDouble();
		double degree = scanner.nextDouble();

		double S = 0.5*a*b*Math.sin(Math.PI*degree/180.0);
		double c = Math.sqrt(a*a+b*b-2*a*b*Math.cos(Math.PI*degree/180.0));

		System.out.printf("%.10f\n",S);
		System.out.printf("%.10f\n", a+b+c);
		System.out.printf("%.10f\n", 2*S/a);
	}
