Explanation / Answer

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

a/sinA=c/sinC

4.5/sin15.8o=6.24/sinC

sinC=(6.24/4.5)sin15.8o

sinC=0.37756

C=22.183o,157.817o

case1:

C=22.183o

A+B+C=180o

B=180-15.8-22.183

B=142.017o

a/sinA=b/sinB

4.5/sin15.8o=b/sin142.017o

b=4.5*(sin142.017o/sin15.8o)

b=10.171

case2:

C=157.817o

A+B+C=180o

B=180-15.8-157.817

B=6.383o

a/sinA=b/sinB

4.5/sin15.8o=b/sin6.383o

b=4.5*(sin6.383o/sin15.8o)

b=1.837
