Below is your formatted code:
#include<iostream>
using namespace std;
int main()
{
int T = 0;
cin >> T;
int x = 0;
int N[T];
int A[T];
int K[T];
int O[T];
for (x = 1; x <= T; x++)
{
cin >> N[x] >> A[x] >> K[x];
}
for (x = 1; x <= T; x++)
{
O[x] = A[x] + (K[x]  1)((360 / N[x])(N[x]  2)  2 * A[x]) / (N[x]  1);
cout << O[x] << " " << 1 << endl;
}
return 0;
}
Two major problems that I found by skimming through the code:
 Start loops from [0,T) or increase all array ranges to T+1.

cout << O[x] << " " << 1 << endl;
You are printing 1 in all of the cases. You are supposed to find the proper fraction and print it. Please see the editorial for more details.
