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())
s = 0.5*a*b*math.sin(math.radians(c))
l = a+b+math.sqrt(a*a+b*b-2*a*b*math.cos(math.radians(c)))
h = 2*s/a
print(s,l,h, sep='\n')
