Question

??

Answer 1

We can find angle C using the fact that the sum of the angles is 180. So do that first.

Answer 2

hello???

Answer 3

48

Answer 4

What is 58 plus 82?

Answer 5

140. So c is 40.

Answer 6

Now use the law of sines to find a

Answer 7

I dont understand what numbers to put in where. I know the law of sines is sin a/a= sin b/b= sin c/c

Answer 8

\[\frac{\sin 40}{8.4}=\frac{\sin 58}{a}\]

Answer 9

\[\frac{\sin 40}{8.4}=\frac{\sin 82}{b}\]

Answer 10

How can sin40/8.4 = both of those?

Answer 11

Because the law of sines says so.

Answer 12

Okay. I get it.sin40/8.4 is .076

Answer 13
