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(int,input().split())

print(a*b*math.sin(math.radians(c))/2)

print((a**2+b**2-2*a*b*math.cos(math.radians(c)))**(1/2)+a+b)

print(a*b*math.sin(math.radians(c))/a)
