Answer 1

Answer:

25, 75

Step-by-step explanation:

Sum of angles of a triangle = 180°

                          3x + x + 80 = 180

                                4x + 80 = 180

                                        4x = 180 - 80

                                        4x = 100

                                          x = 25

one angle (x) = 25°

the other angle (3x) = 25 x 3 = 75°
