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 <stdio.h>
#include <math.h>

using namespace std;

int main(){
	double a,b,c,degree,S;
	scanf("%lf %lf %lf",&a,&b,&degree);
	S = (0.5)*a*b*sin(M_PI*degree/180);
	c = sqrt(a*a+b*b-2*a*b*cos(M_PI*degree/180));
	printf("%.8lf\n",S);
	printf("%.8lf\n",a+b+c);
	printf("%.8lf\n",2*S/a);
}
