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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

class Main{

	public static void main(String[] arg) throws IOException
	{
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String[] str = br.readLine().split(" ");

		double a = Double.parseDouble(str[0]);
		double b = Double.parseDouble(str[1]);
		double degree = Double.parseDouble(str[2]);

		double revrad = 3.141592 * ( (180-degree)/180);

		double cx = b * Math.cos(revrad) + a;
		double cy = b * Math.sin(revrad);

		System.out.printf("%.5f\n",(a*cy) / 2);
		System.out.printf("%.5f\n",Math.sqrt( (Math.pow(cx, 2) + Math.pow(cy, 2) )  ) + a + b);
		System.out.printf("%.5f\n",cy);
	}
