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(int,input().split())

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

print(S)
print(L)
print(h)
