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,input().split())
import math
sinC = math.sin(math.radians(C))
S = a*b*sinC*0.5
c = (a**2 + b**2 -2*a*b*math.cos(math.radians(C)))**0.5
L = a+b+c
h = S*2/a
print(S)
print(L)
print(h)
