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 <stdio.h>
#include <cmath>
using namespace std;
int main(void){
    double a,b,C,S,L,h;
    double P=acos(-1);
    scanf("%lf%lf%lf",&a,&b,&C);
    C=C*P/180;
    S=sin(C)*a*b/2;
    L=a+b+sqrt(a*a+b*b+-2*a*b*cos(C));
    h=b*sin(C);
    
  printf("%.6lf\n%.6lf\n%.6lf\n",S,L,h);  
}
