Law of sines:
a/sin A=b/ sinB
In this case:
24 /sin 92º=7/sin Z
sin Z=(7*sin 92º)/24=0.29148...≈0.29

Z=arc sin (0.29)=16.95º

Answer: Z=16.95º.

3)
Law of cousines:
a²=b²+c²-2bc(cos A)
In this case:
12²=22²+19²-2(22)(19)cos T
144=484+361-836 cos T
-836 cos T=144-484-361
-836 cos T=-701
cos T=-701/-836
cos T=0.83851...≈0.84
T=arc cos (0.84)=33.02

Answer: T=33.02º

cost of 12 tons of sugar...
C(12) = 175(12) + 4500
C(12) = 2100 + 4500
