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 CPP):

Solution:
#include<iostream>
#include<cmath>
#include<cstdio>
using namespace std;

int main(){
  double a, b, C;
  double S, L, h;
  double PI=acos(-1);

  cin >> a >> b >> C;

  S=0.5*a*b*sin(C*PI/180);
  L=a+b+sqrt(a*a+b*b-2*a*b*cos(C*PI/180));
  h=S*2/a;

  printf("%lf\n%lf\n%lf\n", S, L, h);

  return 0;
}
