C = [?]° a = [ ] C = [ ]
Enter

Answer:
a= 10.8 c=4.3
Step-by-step explanation:
Use the law of sines.
a/sin 120=8/sin 40
Which simplifies to: 8*sin (120)/sin (40)
When you put the equation into a calculator, it will answer with 10.77
Therefore, it will be 10.8 if round to the nearest tenth
Using the same concept of the answer to a, the equation will be:
10.8*sin 20/sin 120=4.26
Round to the nearest tenth, and c equals to 4.3
