Answer:
b =6.7
Step-by-step explanation:
We can use the law of sines
We need to find angle B
180 = 82+55+B
180-82-55=B
43 = B
sin 55 sin (43)
------------- = --------------
8 b
Using cross products
b sin 55 = 8 sin 43
Divide by sin 55
b = 8 sin 43 / sin 55
b =6.66053014
To the nearest tenth
b =6.7
Answer:
b = 11.6 cm
Step-by-step explanation:
PRIMERO ENCUENTRAS LA ALTURA DEL TRÍANGULO CON LAS
IDENTIDADES TRIGONOMÉTRICAS COMENSANDO POR EL LADO
IZQUIERDO.
8 cm(sen 82°) = 7.9 cm
AHORA ENCUENTRAS c.
c = 7.9 cm/sen 55° = 9.6 cm
FINÁLMENTE CON LA LEY DE SENOS.
sen 82°/b = sen 55°/9.6 cm
sen 82°/b = 0.0853
b = sen 82°/0.0853 = 11.6 cm
