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>
using namespace std;

#define PI 3.14159265358979

int main(){
 int a,b,c;
 double s,l,h;

 cin >> a >> b >> c ;

 s=a*b*sin(PI*c/180)/2;
 l=a+b+sqrt(a*a+b*b-2*a*b*cos(c*PI/180));
 h=b*sin(c*PI/180);

 cout << fixed << s << endl << l << endl << h << endl ;

 return 0;
