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(){
    cin.tie(0);
    ios::sync_with_stdio(false);
    double a,b,c,C,s;
    cin>>a>>b>>c;
    C=c/180*acos(-1);
    s=a*b*sin(C)/2;
    printf("%.5f\n%.5f\n%.5f\n",s,a+b+sqrt(a*a+b*b-2*a*b*cos(C)),2*s/a);
}
