Answer :

Para resolver el problema de encontrar las funciones trigonométricas para los ángulos dados, aproximadas a cuatro decimales, seguimos los siguientes pasos:

### Paso 1: Convertir los ángulos en forma de grados, minutos y segundos a grados decimales cuando sea necesario.

1. Ángulo [tex]\(b\)[/tex]: 192° 22' 19"
[tex]\[192° + \frac{22'}{60} + \frac{19"}{3600} = 192.372 \text{ grados}\][/tex]

2. Ángulo [tex]\(c\)[/tex]: -45° 10'
[tex]\[-45° - \frac{10'}{60} = -45.1667 \text{ grados}\][/tex]

3. Ángulo [tex]\(d\)[/tex]: 223° 3' 35"
[tex]\[223° + \frac{3'}{60} + \frac{35"}{3600} = 223.0597 \text{ grados}\][/tex]

4. Ángulo [tex]\(g\)[/tex]: -300° 25'
[tex]\[-300° - \frac{25'}{60} = -300.4167 \text{ grados}\][/tex]

5. Ángulo [tex]\(i\)[/tex]: 121° 5' 47"
[tex]\[121° + \frac{5'}{60} + \frac{47"}{3600} = 121.0964 \text{ grados}\][/tex]

6. Ángulo [tex]\(j\)[/tex]: 215° 18' 5"
[tex]\[215° + \frac{18'}{60} + \frac{5"}{3600} = 215.3014 \text{ grados}\][/tex]
