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())
d=a*a+b*b-2*a*b*math.cos(math.pi*c/180)
print(0.5*a*b*math.sin(math.pi*c/180))
print(a+b+d**0.5)
print(b*math.sin(math.pi*c/180))
