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 PYTHON):

Solution:
import math
a,b,c=map(float,raw_input().split())
crad=math.radians(c)
h=b*math.sin(crad)
s=a*h/2
d=(abs((a**2)+(b**2)-(2*a*b*math.cos(crad))))**(0.5)
l=a+b+d
print s
print l
print h
