wait so it says that AAS and SSA are the ones that can be solved using law of sines... but those aren't even any of the choices :/ so is the answer SAS and SSS? since those are used with law of cosines? ;/ so B and D? :/ is that it?

You can use the law of Cosines when u have SAS (2 sides and the angle between them) SSS (all sides)

hero (hero):

Hint: In order to use law of sines, you need angles and sides for one triangle. If you only have all angles, or all sides, law of sines is useless.

ohh so is the answer B and C? SSS and AAA?

5 years ago
OpenStudy (anonymous):

All other choices

5 years ago
OpenStudy (anonymous):

those are the ones that cannot be solved using law of sines? the other ones can?

5 years ago
OpenStudy (anonymous):

SSS and AAA cannot and all the rest can?

5 years ago
OpenStudy (anonymous):

these can

Question: Which of the following problem types CANNOT be solved using the law of sines?

OpenStudy (anonymous):

yeah, which i can't use.. so far, we can't use SSS or AAA? ;/ is that right? SSS and AAA cannot be solved using law of sines?

@Haiqa, I think you're confusing her

5 years ago
OpenStudy (anonymous):

If u have SSS or SAS u can use the law of cosines to solve

5 years ago
OpenStudy (anonymous):

yeah sorry I'm a bit confused :/ but @Hero said that "Hint: In order to use law of sines, you need angles and sides for one triangle. If you only have all angles, or all sides, law of sines is useless." so doesn't that mean that SSS and AAA are useless if applied with law of sines? :/

OpenStudy (anonymous):

If u have SAA AAA ASA You cannot use the law of cosines

hero (hero):

It says "law of sines" not law of cosines @Haiqa

OpenStudy (mertsj):

Why do you keep bringing up the law of cosines? This problem is asking about the law of sines?

Excuse me

hahaa its all good :P

5 years ago
OpenStudy (anonymous):

but I'm still a little lost atm :/ err so SSS and AAA are two of the answers right? since they cannot use law of sines? is that right? :D

5 years ago
OpenStudy (mertsj):

yes

So any time you have two angles (and then can easily figure out the third), it's easy to use the law of sines: ASA or AAS.

5 years ago
OpenStudy (anonymous): 5 years ago
OpenStudy (anonymous):

okay :) so those are the only answers right? since the rest all have a mixture or sides and angles? :)

5 years ago
OpenStudy (anonymous):

With ASA and AAS you can use this law

5 years ago
OpenStudy (anonymous):

U with me?

5 years ago
OpenStudy (anonymous):

mhmm :)

5 years ago
OpenStudy (anonymous):

U can eliminate those answer choices

5 years ago
OpenStudy (anonymous):

but for this problem, the only answers are SSS and AAA right? cuz they CANNOT use law of sines?

hero (hero):

There's one more @iheartfood

5 years ago
hero (hero):

@Haiqa finally pointed out what can be used. So there's more more that can't be used.

5 years ago
OpenStudy (anonymous):

If u have 2 angles and a side or 2 sides and an angle then the law is used. so...

5 years ago
OpenStudy (anonymous):

so are the answers A,B, and C ?

5 years ago
hero (hero):

No

5 years ago
hero (hero):

Why would A be an answer?

5 years ago
hero (hero):

AAS and SAA is the same thing btw

5 years ago
OpenStudy (anonymous):

Remember, SAA has 2 angles and a side

hero (hero):

I don't mean to confuse you @iheartfood

5 years ago
OpenStudy (anonymous):

3 angles (AAA) or 3 sided (SSS) will not be used in this law

5 years ago
hero (hero):

5 years ago
OpenStudy (anonymous):

okay.. but don't the others all have either one side and two angles or two angles and one side? haha and no worries @Hero :) i was kinda confused before haha :P so idk what the third answer would be :(

5 years ago
OpenStudy (anonymous):

Sorry to confuse u. Its pointless to have only 3 angles or only 3 sides

5 years ago
hero (hero):

@Haiqa mentioned what you can use; I mentioned what you can't use. There's only one option left that can't be used.

5 years ago
OpenStudy (anonymous):

no worries haha @Haiqa i meant that i was confused already when i posted lol :P

5 years ago
OpenStudy (anonymous):

ohh so the answers are B,C, and D?? the third one being SAS?

5 years ago
hero (hero):

Finally :D

5 years ago
OpenStudy (anonymous):

hahaa yeah :P sorry y'all! thanks a bunch!!! :D

5 years ago
hero (hero):

Because if you have two sides and only one angle, that's useless. You won't be able to find any more angles unless you use some other law.

5 years ago
OpenStudy (anonymous):

ahh i see... i have another one that's similar to this, but it asks which CAN always be solved using law of cosines OR sines... can i post that here?

5 years ago
OpenStudy (anonymous):

post another question, its so crowded
