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

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

	}
