use law of sines to find angle B

2. kenneyfamily Group Title

would you be able to please walk me through that?

3. kenneyfamily Group Title

wait hold on

4. dumbcow Group Title

$\frac{sinB}{6} = \frac{\sin 62}{4}$

5. kenneyfamily Group Title

ok and then 1.613/25 for C and c

6. dumbcow Group Title

you will get 2 possible answers for B

7. kenneyfamily Group Title

but how does that determine the # of possible solutions?

8. dumbcow Group Title

since you can have 2 answers for B, that leads to 2 answers for c and C as well hence 2 possible triangles

whenever you take the inverse sin to solve you get 2 solutions this comes from unit circle |dw:1353133383544:dw|
