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) {
		// TODO 自動生成されたメソッド・スタブ
		Scanner sc = new Scanner(System.in);
		int a = sc.nextInt();
		int b = sc.nextInt();
		int deg = sc.nextInt();
		double s,l,h;

		s = a * b * Math.sin(deg * Math.PI / 180) / 2;
		l = a + b + Math.sqrt(a * a + b * b - 2 * a * b * Math.cos(deg * Math.PI / 180));
		h = b * Math.sin(deg * Math.PI / 180);

		System.out.println(s + " " + l + " " + h);
	}
