Precalculus, Chapter 6, 6.1, Section 6.1, Problem 24

Given: C=95.20^@, a=35, c=50
Law of Sines a/sin(A)=b/sin(B)=c/sin(C)
35/sin(A)=b/sin(B)=50/sin(95.20)
35/sin(A)=50/sin(95.20)
sin(A)=[35sin(95.20)]/50
sin(A)=.6971
A=arcsin(.6971)
A=44.20^@

B=180-95.20-44.20
B=40.60^@

b/sin(40.60)=50/sin(95.20)
b=[50sin(40.60)]/sin(95.20)
b=32.67
