Write C++ Program to find Third Angle of Triangle if Two Angles Are Given

// CPP Program to find Third Angle of Triangle if Two Angles Are Given

#include <iostream>

using namespace std;

int main()
{
    int a1, a2, a3;

    cout << "Enter Angle 1 :--> ";
    cin >> a1;

    cout << "Enter Angle 2 :--> ";
    cin >> a2;

    a3 = 180 - (a1 + a2);   //sum of all the angles is 180

    cout << "Third angle of the triangle :--> " << a3;

    return 0;
}

Output:

Enter Angle 1 :--> 30
Enter Angle 2 :--> 80

Third angle of the triangle :--> 70
