//формулы сам(а) добавишь в программу
#include <iostream>
#include <cmath>
using namespace std;
int main()
{
 int choose = 0;
int a, b, alpha, beta, formula, basis, height, square;
cout << "Input your number(1-3):" << endl;
cout << "1.Enter two parties of a triangle and a corner between them:" << endl;
cout << "2.Enter parties of a triangle and two corners:" << endl;
cout << "3.Enter basis and height:" << endl;
 cin >> choose;
switch (choose)
  {

  case 1:
  cin >> a >> b >> alpha;
  //formula =
  cout << "formula = " << formula;
  cout << endl;

 case 2:
     cin >> a >> beta >> alpha;
   //formula =
   cout << "formula = " << formula;
   cout << endl;

  case 3:
     cin >> basis >> height;
   //square = 
  cout << "square = " << square;
  cout << endl;

 default:
  cout << "Wrong number!";
 }
return 0;
