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>
#include <stdio.h>
using namespace std;
int main(){

double a,b,C,S,L,h;
cin>>a>>b>>C;

S=a*b*sin((C/180)*M_PI)/2;
L=a+b+sqrt(a*a+b*b-2*a*b*cos((C/180)*M_PI));
h=S*(double)2/a;

printf("%.8f\n%.8f\n%.8f\n",S,L,h);

}
