Answer:

Explanation:

We know by the Triangle Angle-Sum Theorem that the angles of a triangle all add up to equal 180. So we find angle B:

180 - 82 - 55 = 43

So angle B = 43. Now we can use the Law of Sines to solve for side b:


(sin(55))/(8)=(sin(43))/(b)

Cross multiply to get

b sin(55) = 8 sin(43) and divide to solve for b:


b=(8sin(43))/(sin(55)) so

b = 6.6605
