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

a, b, C = map(float, raw_input().split())

sinC = math.sin(math.radians(C))
cosC = math.cos(math.radians(C))
c = math.sqrt( a*a + b*b - 2*a*b*cosC )

print ( a * b * sinC ) / 2  # Area
print a + b + c             # Periphery
print b * sinC              # Height
