Solution

Para convertir radianes a grados, utilizamos la relación de que π radianes equivalen a 180 grados.

  1. Comenzamos con la cantidad de radianes que se han movido: 23π-\frac{2}{3}\pi radianes.
  2. Utilizamos la relación de conversión: 1 radian=180π grados1 \text{ radian} = \frac{180}{\pi} \text{ grados}.
  3. Multiplicamos la cantidad de radianes por la relación de conversión:

23π radianes×180π grados/radian=23×180 grados -\frac{2}{3}\pi \text{ radianes} \times \frac{180}{\pi} \text{ grados/radian} = -\frac{2}{3} \times 180 \text{ grados}

  1. Simplificamos la expresión:

23×180=120 grados -\frac{2}{3} \times 180 = -120 \text{ grados}

Por lo tanto, las manecillas del reloj se han movido 120-120 grados.
