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

  double a,b,c,PI=3.1415926535;
  cin >> a >> b >> c;
  printf("%.5f\n",a*b*sin(c*PI/180)/2);
  printf("%.5f\n",sqrt(a*a+b*b-2*a*b*cos(c*PI/180))+a+b);
  printf("%.5f\n",b*sin(c*PI/180));
