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
from math import radians, sin, cos

a, b, r = map(float, raw_input().split())
r = radians(r)
h = b * sin(r)
c = (a**2 + b**2 - 2*a*b*cos(r))**0.5
l = a + b + c
s = a * h / 2
print s
print l
print h
