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 scan = new Scanner(System.in);

		double a = scan.nextDouble();
		double b = scan.nextDouble();
		double C = scan.nextDouble();

		double h = Math.sin(Math.PI * C / 180) * b;
		double S = a * h / 2;
		double L = a + b + Math.sqrt(a * a + b * b - 2 * a * b * Math.cos(Math.PI * C / 180));

		System.out.println(S);
		System.out.println(L);
		System.out.println(h);
		scan.close();
		System.exit(0);
	}
