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())
c = c / 180 * math.pi

print "%.10f" % float(a*b*math.sin(c)/2)
x = math.sqrt(a**2 + b**2 - 2 * a * b * math.cos(c))
print "%.10f" % float(a + b + x)
print "%.10f" % float(b*math.sin(c))
