A place for pasta ๐ and wabby ๐ฆ no lurking please ๐๐
I made this cause I couldn't find both of you anywhere XDD, and because I like making forum post ๐คฃ๐คฃ

My handwriting is very poor, I hope you can see it , and image weren't uploading.
@ThornyNini
Ooppss sorry those two aren't loadings, gimme a secย
@littlenini16 omg ilyyyy ur the best fr nini๐ญ๐ญ u saved my *** from the math teacher i will forever be thankful fr๐ญ๐ญโฅโฅ
@PastaIsVeryUnderrated
Am never writing, I showed you another simpler way to solveย
@littlenini16
@sebastian0o0
ima be spamming this forum in my free time sorry not sorry ๐
@PastaIsVeryUnderrated both of those tags didnt work๐ญ
@PastaIsVeryUnderrated ur so meannnn๐ฅบ
bruh i tagged nini twice w her old username wtf๐ญ๐ญ๐ญ๐ญ
@PastaIsVeryUnderrated
Haha, I kinda miss little Niniย
@Sebastian0o0
@PastaIsVeryUnderrated
Spaghettiiiii see sebnicorn is been mean,and that's my Job๐๐ *pokes seb*
@Sebastian0o0
*Pokes eyes* now you can't roll them anymore ๐ค๐ค๐ค...
@ThornyNini ouchhhh๐ญ๐ญ immm sorryyyyyyyyyyyyyyyyy 4'10 (is)nt very shortttt
@Sebastian0o0
*Cuts one feet and four inches from unicorn and adds it to mine ,now whose little ๐๐
@ThornyNini i saiidddd itssss nottt shortttttttttt๐ญ
@Sebastian0o0
You bracketed (Is), smhhhhhhhhhhh ๐๐
@ThornyNini u caught me๐ im really sorry๐ญ
@ThornyNini "thats my job" said nini innocently๐๐๐
@PastaIsVeryUnderratedย
Uh huh cause am an angel ๐ ๐ย
XDD, a mean angel at thatย
@ThornyNini that kinda defeats the purpose of bein an angel nini...
@PastaIsVeryUnderrated
Which basically means, I'm the exact opposite of an angel, the devil lol
@PastaIsVeryUnderrated
XDD , you can also solve it using this way , I think this one should be easier, since my handwriting looks like squashed tomatoes ๐คฃ ๐คฃ ๐คฃ, am typing instead.
Given:
AD โฅ BC (AD is parallel to BC)
โ B = 90ยฐ (right angle)ย
AB = 3 cm
AD = 6 cm
BC = 10 cm
Sooooo, let's find the length of CD:
Since AD โฅ BC, we can use similar triangles:
CD/BC = AB/AD
CD/10 = 3/6
CD = 5 cm
Finding โ DCB and โ ACB:
Using the right triangle BCD:
tan(โ DCB) = BC/CD = 10/5 = 2
Using right triangle ABC:
tan(โ ACB) = BC/AB = 10/3
cos(โ ACB) = AB/AC
To find AC, use the Pythagorean theorem:
ACยฒ = ABยฒ + BCยฒ
ACยฒ = 3ยฒ + 10ยฒ
AC = โ(109)
cos(โ ACB) = 3/โ109
Calculate::
cos(โ DCB) = CD/BC = 5/10 = 1/2
Using the addition to solve tangentย
tan(โ DCB - โ ACB) = (tan(โ DCB) - tan(โ ACB)) / (1 + tan(โ DCB)tan(โ ACB))
Substitute the values::ย
tan(โ DCB - โ ACB) = (2 - 10/3) / (1 + 2*10/3)
tan(โ DCB - โ ACB) = (6/3 - 10/3) / (1 + 20/3)
tan(โ DCB - โ ACB) = -4/3 / (23/3)
tan(โ DCB - โ ACB) = -4/23
Calculating cos(โ DCB) - tan(โ ACB):
cos(โ DCB) - tan(โ ACB) = 1/2 - 10/3
cos(โ DCB) - tan(โ ACB) = 3/6 - 10/3
cos(โ DCB) - tan(โ ACB) = 1/2
Therefore:
cos(โ DCB) - tan(โ ACB) = 1/2
*Bows* Ahh Thank you
@Sebastian0o0
Am not smart ๐๐, an average, no medium, just a teensie tiny bit of smart ๐คฃ
@ThornyNini omg nini ur absolutely amazing๐ญ๐ญ๐ญ and gurll u think u aint smart? smhhh
@PastaIsVeryUnderrated
My brain is a marshmallow ๐๐
@ThornyNini smartest marshmallow in da world apparently
@Sebastian0o0
I dunno..... Ermmmmmm....,after writing seb a unicorn popped up,so I went with the flow ๐๐
@Sebastian0o0
Nooooo your still sebbyyyywabbbyy, and sebnicorn now.
Still want help with homework,ย ย just not maths my poor brain ain't braining anymore ๐ฅฒย
@ThornyNini im glad i dont want to be unicorn๐ alsooo the only hw i have is mathss buttttt ai can do it for me i dont want to put u through anymore of the mental torment that is maths
