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

		//Math.PI→円周率
		double Cc = C * Math.PI / 180;

		double L = a + b + Math.sqrt((a * a) + (b * b) - 2 * a * b * Math.cos(Cc));
