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())
C_rad = C / 180 * math.pi
 
H = b * math.sin(C_rad)
S = H * a / 2 
L = math.sqrt( (a-b*math.cos(C_rad)) **2 + H**2 ) + a + b

print(S)
print(L)
print(H)
