Answer 1

Respuesta:

$180 = A + B + C \\ 180 = 30 + 70 + B \\ B = 180 - 70 - 30 \\ B = 80 \\ \frac{ \sin(A) }{a} = \frac{ \sin(B) }{b} \\ a = \frac{b \times \sin(A) }{ \sin(B) } \\ a = \frac{15 \times \sin(30) }{ \sin(80) } \\ a = 7.62 \\ \frac{ \sin(A) }{a} = \frac{ \sin(C) }{c} \\ c = \frac{a \times \sin(C) }{ \sin(A) } \\ c = \frac{7.62 \times \sin(30) }{ \sin(70) } \\ c = 4.05$
