The Theorem of the sum of the angles of any triangle is a topic covered in Geometry in elementary and high school. It is always present in problem situations in math questions in entrance exams, college entrance exams, and the ENEM (Brazilian National High School Exam). To calculate the value of x in the triangle, we first write the sum of its measures (values ​​of the angles) and equate it to 180º, then we solve the resulting equation using the most practical method we know.
