Question

Sendo R paralela a S e T calcule as medidas na figura

Answer 1

    Pela definição de ângulos entre paralelas cortadas por secante

                   47° + 38° + x = 180   
                                      x = 180 - (47 + 38)
                                         = 95
                                                            x = 95°

                  38 + x + y = 180°
                  38 + 95 + y = 180°
                                  y = 180 - (38 + 95)
                                     = 47
                                                           y = 47°
