Given a triangle A B C with A = 30 ∘ , b = 50 , and c = 40 Find angle B

Question

Given a triangle   A B C   with    A = 30 ∘ ,      b = 50   , and   c = 40   Find angle   B

Steven K. · Accepted Answer

Apply the Law of cosines two times: (1) 402+502-2(40)(50)cos 30=BC2 so BC=25.21(2) 502=402+25.212-2(40)(25.21)cos B, so cos B = negative 0.13 and B = 97.5 degrees
