Solution

5) by law of sines a/sinA=b/sinB=c/sinC

a/sinA=c/sinC

4.1/sin11.8^o=6.85/sinC

sinC=(6.85/4.1)sin11.8^o

sinC=0.341658

C=19.98^o,160.02^o

case1:

C=19.98^o

A+B+C=180^o

11.8^o+B+19.98^o=180^o

B=148.22^o

b/sinB=a/sinA

b/sin148.22^o=4.1/sin11.8^o

b=4.1sin148.22^o/sin11.8^o

b=10.56

case2:

C=160.02^o

A+B+C=180^o

11.8^o+B+160.02^o=180^o

B=8.18^o

b/sinB=a/sinA

b/sin8.18^o=4.1/sin11.8^o

b=4.1sin8.18^o/sin11.8^o

b=2.85
