Problem:
Triangle

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.

Sample Input

4 3 90

Sample Output

6.00000000
12.00000000
3.00000000

Solution in JAVA (judge verdict: Wrong Answer)

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 rad = Math.toRadians(C);
		double cos_c = Math.toRadians(rad);
		double c2 = a * a + b * b - 2 * a * b * cos_c;
		double c = Math.sqrt(c2);
		double sin_c = Math.toRadians(C);
		double S = a * b * sin_c / 2;
		double h = b * sin_c;
		double L = a + b + c;
		System.out.println(S);
		System.out.println(L);
		System.out.println(h);
	}
