Question

Aplicar ley de senos

Answer 1

Respuesta:

$40 + 137 + N = 180 \\ N = 180 - 137 - 40 \\ N = 3 \\ \frac{ \sin(R) }{r} = \frac{ \sin(H) }{h} \\ h = \frac{ \sin(H) \times r}{ \sin(R) } \\ h = \frac{ \sin(137) \times 9 }{ \sin(40) } \\ h = 9.55 cm\\ \frac{ \sin(R) }{r} = \frac{ \sin(N) }{n} \\ n= \frac{ \sin(N) \times r}{ \sin(R) } \\ n = \frac{ \sin(3) \times 9 }{ \sin(40) } \\ n= 0.73cm$
