The angles of a triangle are 80º, 2x + 2º, and 5xº. what is the value of x?
(i'm a k12 student taking a semester test)

Since the sum of the angles of a triangle = 180°

Then  80º + (2x + 2)º + 5xº  = 180°
                          82° + (7x)° = 180°
                                    (7x)° = 180° - 82°
                                        x   =  98° ÷ 7
                                    ∴  x   = 14

4038 is the answer lol just use a calculator
