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 = (a*b*math.sin(math.pi*c/180))/2
l = math.sqrt(a**2+b**2-2*a*b*math.cos(math.pi*c/180))+a+b
h = s*2/a
print(s)
print(l)
print(h)
