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
e=map(float,raw_input().split())
a=e[0]
b=e[1]
C=math.radians(e[2])
c=(a**2+b**2-2*a*b*math.cos(C))**0.5
h=b*math.sin(C)
S=h*a*0.5
L=a+b+c
print S
print L
print h
