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,r=[float(k) for k in input().split()]
S=a*b*math.sin(math.radians(r))/2
L=math.sqrt(a**2+b**2-2*math.cos(math.radians(r))*a*b)+a+b
H=S*2/a
print(S,L,H,sep='\n')
