Answer:
 6.7 cm
Step-by-step explanation:
To make use of the Law of Sines for finding b, you need to know the missing angle B. Since the sum of the angles of a triangle is 180°, you can find angle B as ...
 B = 180° -82° -55° = 43°
Now, you put the numbers you know into the formula given and solve for b.
 sin(A)/a = sin(B)/b
 sin(55°)/(8 cm) = sin(43°)/b
Cross multiplying gives ...
 b·sin(55°) = (8 cm)·sin(43°)
and dividing by the coefficient of b gives you ...
 b = (8 cm)·sin(43°)/sin(55°) ≈ 6.7 cm
