OpenStudy (anonymous):

sin(20 degrees) = ?/?

OpenStudy (elisaneedshelp):

= x/12 .... or 12/x

OpenStudy (anonymous):

it's one or the other. SOH CAH TOA

OpenStudy (anonymous):

sin = opp/hyp

OpenStudy (elisaneedshelp):

sin(20 degrees) = 12/c

OpenStudy (anonymous):

that's correct. How would we get c?

OpenStudy (elisaneedshelp):

i cant remember

OpenStudy (anonymous):

you can use algebra.\[\huge \sin(20) = \frac{ 12 }{ c }\]\[\huge c = \frac{ 12 }{ \sin(20) }\]

OpenStudy (elisaneedshelp):

35.09?

OpenStudy (anonymous):

it would seem so

OpenStudy (elisaneedshelp):

i hope so...

OpenStudy (anonymous):

I wouldn't intentionally give you a wrong answer :(

OpenStudy (elisaneedshelp):

OpenStudy (anonymous):

one or two problems

OpenStudy (elisaneedshelp):

i just hate my life

OpenStudy (anonymous):

ugh I wish I could stay up all night and console you. An F isn't going to ruin your life. In a few years you're going to look back at high school and realize how insignificant it all was

OpenStudy (anonymous):

That isn't very important either. The way you spoke about him it didn't seem like he was very good for you. Just put work into things like school and focus less on trivial high school relationships. . It'll pay off.

OpenStudy (anonymous):

oh sweet. he's a grown man with the maturity level of a high schooler.

OpenStudy (anonymous):

meh I'm not gonna counsel you

OpenStudy (anonymous):

post a problem or I'll just get to bed, sorry

OpenStudy (elisaneedshelp):

how about #12 on the same picture

OpenStudy (anonymous):

which trig identity relates a and b from angle B?

OpenStudy (elisaneedshelp):

idk whether CAH or TOA

OpenStudy (elisaneedshelp):

im sure you already went to sleep so whatever screw everything
