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 <bits/stdc++.h>
using namespace std;
int main(){
double a,b,c,h;
cin>>a>>b>>c;
h=b*sin(M_PI*c/180);
printf("%f\n%f\n%f\n",a*h/2,a+b+sqrt(( a-(b*cos(M_PI*c/180)) )*( a-(b*cos(M_PI*c/180)) )+h*h),h);
return 0;
}
