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);
		String str = scan.nextLine();
		String[] distance = str.split(" ");
		
		double a = Double.parseDouble(distance[0]);
		double b = Double.parseDouble(distance[1]);
		double C = Double.parseDouble(distance[2]);
		
		double S = a * b / 2;
		double L = Math.pow(((Math.pow(a, 2) + (Math.pow(b, 2)))), 0.5) + a + b;
		double h = (2 * S) / a;
		
		System.out.printf("%.8f\n",S);
		System.out.printf("%.8f\n",L);
		System.out.printf("%.8f\n",h);
	}
