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>

using namespace std;

int main() {
    int a, b, C;
    cin >> a >> b >> C;
    double rad = C * M_PI / 180;
    double h = sin(rad) * b;
    double S = a * h / 2;
    double L = a + b + (sqrt(a * a + b * b - (2 * a * b * cos(rad))));
    printf("%f\n%f\n%f\n", S, L, h);
}
