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) {
		try (Scanner sc = new Scanner(System.in);) {
			double a = sc.nextDouble();
			double b = sc.nextDouble();
			double c = sc.nextDouble();
			//２点間の距離
			double s = (a * b / 2 * Math.sin(Math.toRadians(c)));
				System.out.println(s);
			double l = (a + b +Math.sqrt(Math.pow(a, 2) + Math.pow(b, 2) - 2 * a * b
					* Math.cos(Math.toRadians(c))));
				System.out.println(l);
			double h = (b * Math.sin(Math.toRadians(c)));
				System.out.println(h);
		}
	}
