Answer:  A = 122°

Step-by-step explanation:

sin13°+cos13°/sin13°-cos13°

                                                    = tan13°+1/tan13°-1

                                                   = 1+tan13°/-(1-tan13°)

                                                   = -(tan45°+tan13°)/1-(tan45°)(tan13°)

                                                   = -(tan(45°+13°))

                                                   = -tan58°

                                                   = tan(180°-58°)

                                                   = tan122°

given rhs = tan A

so tan 122° = tan A

therefore, A = 122°
