As anyone willing to help me for today? I have Alot and i will really appreciate it

OpenStudy (anonymous):

Of course. What do you need help with?

OpenStudy (elisaneedshelp):

Omg thank you well for the first question is the tangent of <a 16/30 ?

OpenStudy (anonymous):

Way above my level but i know someone here can help you! LOL I am a 6th grader.

OpenStudy (anonymous):

Oh my goodness! I am afriad I can't help you there. I know someone who can though. (@OrangeMaster )

OpenStudy (elisaneedshelp):

can you help me with geometry proofs?

OpenStudy (elisaneedshelp):

@anyuying you never said who could help me

OpenStudy (elisaneedshelp):

im a 10th grader

OpenStudy (elisaneedshelp):

@OrangeMaster you were recommended

OpenStudy (elisaneedshelp):

@jdoe0001 can you help me

OpenStudy (jdoe0001):

what ... are you solving?

OpenStudy (elisaneedshelp):

6)Draw triangleABC such that m<C= 90*, AB=25 and side AC= 19. Find <A (<α ).

OpenStudy (jdoe0001):

well... I've seen it....but you've got the cotangent already :)

OpenStudy (elisaneedshelp):

wait so do you mean for this problem all i have to do is find the cotangent?

OpenStudy (nikato):

|dw:1394409925129:dw| so SOH CAH TOA what will you use for this problem

OpenStudy (jdoe0001):

ElisaNeedsHelp ... well.. the picture doesn't really tells us what you're after :) in the previous posting you were looking for the cotangent I recall

OpenStudy (nikato):

oh yes^ for you first question, you are correct. based on your diagram, the tangent ratio is 16/30

OpenStudy (elisaneedshelp):

CAH? @nikato

OpenStudy (nikato):

correct. now can you write an equation for it using CAH or cos

OpenStudy (elisaneedshelp):

wait but the adjacent is missing so SOH?

OpenStudy (nikato):

no. you have the adjacent but you dont have the opposite side so you cant use SOH

OpenStudy (elisaneedshelp):

buts isnt the opp and adj here

OpenStudy (elisaneedshelp):

OpenStudy (nikato):

im not quite sure what i was suppose to see in that pic. but... the opp and adj depends on your theta(reference) angle for example |dw:1394410987789:dw|
