Answer 1

Beatriz,
Vamos paso a paso

Formulamos una regla de tres simple tomando como referencia
             360° = 2π rad
        o
             180° = π
                                         180°                π
                                          G                    π/4

                                               G = [180 * (π/4)]/π
                                                   = 180/4
                                                   = 45

                                                               π/4 rad = 45°
