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
import math
a, b, C = map(float, input().split())
C = math.radians(C)
print(1/2 * a * b * math.sin(C))
c = (a ** 2 + b ** 2 - 2 * a * b * math.cos(C)) ** 0.5
print(a + b + c)
print(b * math.sin(C))
