C++ Exercises: Enter two angles of a triangle and find the third angle

C++ Basic: Exercise-52 with Solution

Write a program in C++ to enter two angles of a triangle and find the third angle.

Pictorial Presentation:

Sample Solution:

C++ Code :

#include<iostream>
using namespace std;
 
int main()
{
    float ang1, ang2, ang3;
	cout << "\n\n Find the third angle of a triangle :\n";
	cout << "-----------------------------------------\n";	
    cout<<" Input the 1st angle of the triangle : ";
    cin>>ang1;
    cout<<" Input the 2nd angle of the triangle : ";
    cin>>ang2;
	ang3=180-(ang1+ang2);
    cout << " The 3rd of the triangle is : " << ang3 << endl;
	cout << endl;
    return 0;
}

Sample Output:

Find the third angle of a triangle :                                  
-----------------------------------------                              
 Input the 1st angle of the triangle : 35                              
 Input the 2nd angle of the triangle : 35                              
 The 3rd of the triangle is : 110
