WAP in C++ to Find the third angle of a Triangle

The Program in C++ to Find the third angle of a Triangle is given below:

``````#include <iostream>
using namespace std;

int main() {
double angle1, angle2, angle3;

cout << "Enter first angle of the triangle: ";
cin >> angle1;

cout << "Enter second angle of the triangle: ";
cin >> angle2;

angle3 = 180 - angle1 - angle2;

cout << "Third angle of the triangle: " << angle3 << endl;

return 0;
}
``````

Output:

Enter first angle of the triangle: 45
Enter second angle of the triangle: 89
Third angle of the triangle: 46

Pro-Tips💡

In this program, the user is prompted to enter the first and second angles of the triangle.

These angles are then stored in the variables `angle1` and `angle2`.

The third angle is then calculated using the formula `angle3 = 180 - angle1 - angle2`,

which is based on the fact that the sum of the angles of a triangle is always 180 degrees.

The resulting third angle is then displayed on the screen.
