Area of Triangle Revised

Question: You are given the two sides and the inner angle of n-triangles. Find and show the total area and the area of the triangle which has the smallest area.

Input specification
You will be first given a number (n) the number of triangles. Then, in the following n lines you will be given two integers: the two sides of triangle (a and b). Then in the following n lines, you will be given the angle in degrees between the two given sides where 0 ≤ n ≤ 5000, and 0 ≤ angle ≤ 180 and 0 ≤ (a,b) ≤ 500.

Output specification:
Show two floating point numbers with 2 digits precision: total area of the triangles and the area of the triangle with the smallest area.
