tolong bantu hbs bsk dikumpul no 26 dan 27

26. 5x+ 11° =136°  <---> 5x +11°= 136°
                                               5x = 136° -11°
                                               5x = 125
                                                 x = 125° / 5
                                                 x = 25°
      y - 2° = 38° <---> y - 2° = 38°
                                        y = 38° + 2°
                                        y = 40°
      2z - 8° = 98°  <---> 2z - 8° = 98°
                                           2z = 98° + 8°
                                           2z = 106°
                                            z = 106°/2
                                            z = 53°
 sehingga nilai  x+y+z = 25°+40°+53° = 118°
