Given three integer numbers and knowing that they form a valid triangle as:(int side1, int side2, int side3), how can I use a single c++ statement to test if an angle is obtuse

If the squares of one side is langer than the sum of squares of the other sides, the opposite angle is obtuse.

Just find the longest side and use the law of cosines only once.
