@Hero

princeevee:

@ThisGirlPretty is jhony on?

princeevee:

@Vocaloid

princeevee:

@imqwerty

Silver:

TanB= (side opposite to angle B)/(side adjacent to angle B which isn't the hypotenuse)

princeevee:

YX is the hypotenuse, right?

Silver:

There's no YX in the figure wym

Silver:

The longest side is the hypotenuse

princeevee:

i got somewhere near the bottom right one

jhonyy9:

@princeevee hi - do you now the tangent law what say ?

jhonyy9:

do you know - sorry

princeevee:

i can take a recap

jhonyy9:

ok i wait it

jhonyy9:

just bc. your answer not is right

jhonyy9:

or than you know the law of sin and cos and you know that tan = sin/cos so from these you can deduct the tangent law easy

jhonyy9:

@ThisGirlPretty your opinion about this above wrote please

jhonyy9:

@princeevee please collaborate i like help you

princeevee:

sorry,

jhonyy9:

how you ve wrote above take a recap and please write me the law of tan

jhonyy9:

tan B = ?

jhonyy9:

what side divide what side ?

princeevee:

uh, 8?

jhonyy9:

8 mean adjacent side divide what ?

jhonyy9:

so like a tutorial for example sin B = opposite side divide hypothenuse right ?

jhonyy9:

@ThisGirlPretty please

jhonyy9:

@princeevee do you wan collaborate please ?

princeevee:

sorry, it takes me a while.

jhonyy9:

you ve learned the law of tan ?

jhonyy9:

@princeevee than you dont write nothing i will go - sorry i not can giving you the right answer

jhonyy9:

@princeevee courage - step by step i like help you - this is easy just you need to know the law of tan

jhonyy9:

do you wann recap again the law of tan please ?

princeevee:

the law of tan is used when you have two sides and an included angle shown, right?

jhonyy9:

now in this case this not is importantly i ve wrote you the tutorial above for example the law of sin say sinus of an angle equal opposite side divide hypothenuse so like this how is the law of tan please ?

jhonyy9:

on your posted image this is a right triangle - yes ?

princeevee:

yeah

jhonyy9:

so from this result that you can deciding easy what side is the hypothenuse

princeevee:

the angled side

jhonyy9:

so you dont know directly the law of tan ? than we can calcule it from this above wrote proportionality tan B = sin B / cos B do you know sin B = ?

jhonyy9:

i ve wrote it above please check it

jhonyy9:

sin B = op. / hyp

jhonyy9:

ok ? than cos B = ?

jhonyy9:

please !!!

princeevee:

sorry, my internet is really buggy!

jhonyy9:

ok. but than how can i help you ?

princeevee:

so sin5 = op./13?

princeevee:

i mean 17

princeevee:

and 8

jhonyy9:

sorry i dont understand from this nothing

jhonyy9:

please answer my question firstly i ve wrote above what is sin B so can you writing cos B = ?

jhonyy9:

than sinus of an angle equal opposite side divide hypothenuse so cosinus of an angle how will be ?

jhonyy9:

@princeevee this is so difficilly ?

princeevee:

my internet is bad, sorry it will take me some time

jhonyy9:

sin = op. / hyp cos = adj./hyp. right ?

princeevee:

yeah

jhonyy9:

and from this now you can easy getting tan = sin /cos tan B = (op/hyp)/(adj./hyp) = ?

princeevee:

alright

jhonyy9:

you need simplify it

jhonyy9:

the first fraction multiply by second inversed and simplify by hyp - so what will remain there ?

jhonyy9:

@ThisGirlPretty right ?

jhonyy9:

@sillybilly123 your opinion please ? ty

sillybilly123:

slow down, compadre

sillybilly123:

not everyone is that quick

jhonyy9:

tan B = (op/hyp)/(adj./hyp) = (op/hyp) *(hyp/adj) = ?

jhonyy9:

@princeevee said that the law of tan ve learned - so than ??? but i understand you @sillybilly123 - i think

jhonyy9:

@princeevee you can simplify by hyp and than what will get ?

princeevee:

so we try to find the multiple of the hypotenuse?

jhonyy9:

no you can simplify by hypothenuse there and will get tan B = ?

princeevee:

tan 8/15?

jhonyy9:

no you need getting tan B = what side divide what side clearly please ?

jhonyy9:

hyp from the denominator of first fraction divide by hyp from numerator of second fraction - so than what will remain there ? tan B = ? / ?

princeevee:

15/17? i'm getting really confused...

jhonyy9:

17 not can being bc. 17 mean hypothenuse

jhonyy9:

15 is right

jhonyy9:

@princeevee attention please - than hyp by hyp simplify so than what will remain there again ?

princeevee:

so 15/8 then?

jhonyy9:

ok and with words the law of tan what say tan B = ?/?

jhonyy9:

15 is opposite side and 8 what is ?

princeevee:

the numerator?

jhonyy9:

no this side with 8 what side is to angle B ?

jhonyy9:

than this side with 15 is opposite side of angle B

jhonyy9:

above i ve wrote it what mean this adj. ?

princeevee:

BC?

jhonyy9:

op mean oposite side and adj. mean adjacent side so result tan B = op / adj. = 15/8 what mean this what choice is right ?

jhonyy9:

hope this is now understandably for you ok. ?

princeevee:

the bottom right one.

jhonyy9:

there is 15/8 sure ?

princeevee:

yeah, seems so..

jhonyy9:

@ThisGirlPretty can you explain it more please

jhonyy9:

sorry but this 15/8 i see on the left column

jhonyy9:

bottom on the left side - yes @ThisGirlPretty ?

jhonyy9:

so this is the correct answer was difficily ? but hope you understand it now clearly sure

jhonyy9:

sorry but i need to go sleeping bc. here is in the night 0,58 o"clock was my pleasure -and any time good luck bye bye

princeevee:

okay..
