How would I use the law of sines for this problem?

Question

dtan5457 · Answer

Give that a=112 degrees
a=9
b=4

This is SSA, how would I know if this measurment would determine one triangle, two triangles, or no triangle.?

anonymous · Answer

draw it

dtan5457 · Answer

if i'm trying to get sin b would I get
$$sinb=\frac{ 4\sin112 }{ 9 }$$

anonymous · Answer

yes

anonymous · Answer

but i really recommend you draw the triangle

@satellite73  why is your smart score 20?

dtan5457 · Answer

with two sides im not sure what it should look like

anonymous · Answer

because i am not very smart

SSA means that you have a triangle where 2 of the sides are congruent and share an angle?..... Im not sure.

anonymous · Answer

what do you think it is supposed to be?
what mode is  your calculator in?

anonymous · Answer

SSA just means you know two sides and an angle

anonymous · Answer

not the angle between the two sides

dtan5457 · Answer

Oh, thank you, I plugged it in wrong, I see now

anonymous · Answer

i don't know why they use SSA, i would use retrice

anonymous · Answer

lol retrice

dtan5457 · Answer

so yeah, i got roughly 24 degrees. now for the amount of triangles..

jhannybean · Answer

Oh okay.

dtan5457 · Answer

Since a>b, according to my book, there is one triangle to form, correct?
