Problem: 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

Solution (in PYTHON3):

Solution:
import math

a,b,C= map(float,(input().split()))
Crad=C/180*math.pi

H = b*math.sin(Crad)
S = H * a/2


L=math.sqrt((a-b*math.cos(Crad))**2+H**2)+a+b
print(S)
print(L)
print(H)
