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:
from math import sin,cos,pi,sqrt
a,b,C = map(int,input().split())
h = b * sin(pi*C/180)
S = a  * h * 1/2
L = sqrt(a**2+b**2-2*a*b*cos(pi*C/180)) + a + b
print(S)
print(L)
print(h)
