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;
    cin >>a >>b >>C;
    double S2=a*b*sin(C*M_PI/180);
    double S=S2/2;
    double L=a+b+sqrt(a*a+b*b-2*a*b*cos(C*M_PI/180));
    double h=S2/a;
    cout <<fixed <<setprecision(10) <<S <<' ' <<L <<' ' <<h <<endl;
    return 0;
