Respuesta :

Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : [tex]\frac{sin 42}{a} = \frac{sin 55}{175}[/tex] ⇔ [tex]a = sin42 \frac{175}{sin 55}[/tex] ⇔ a= 142.95

Parte3 :

Using the same law : [tex]c = sin 83\frac{a}{sin 42}[/tex]  or  [tex]c= sin 83\frac{175}{sin 55}[/tex]  ⇔ c= 212.04
