With this app the user can solve any triangule. A triangule has 3 sides and 3 angles. Solving the triangule consists of introducing three values of the triangule and getting the other three.
Therefore, firstly the user has to introduce three values (one of them has to be a side). The app will use the cosine theorem and the sine theorem (and the sum of the 3 angles of the triangule is 180 degrees) to calculate the other three values.
You have to introduce the angles as sexagesimal degrees.
The app explains all the steps to get the solution.
