i need help in geometry can anyone help me please?

OpenStudy (anonymous):

but math is geometry so i think i'm in the right place plus barely anyone replies there @TheRealMeeeee

OpenStudy (therealmeeeee):

I was just saying where it belongs :P

OpenStudy (jdoe0001):

I was wondering what's a "dimon" =) but anyhow, posting something specific helps

OpenStudy (therealmeeeee):

@jdoe0001 if you want to know that you should PM him

OpenStudy (therealmeeeee):

You are getting off topic a little bit

OpenStudy (anonymous):

What do you need help with in math.. seriously geometry is math moving on

OpenStudy (anonymous):

thank you @warrior2015 and do you want me to post the question

OpenStudy (anonymous):

Yes please do! I will try my best to help!

OpenStudy (anonymous):

thank you so much Look at the figure. If tan x° = z divided by 10 and cos x° = 10 divided by y, what is the value of sin x°?

OpenStudy (anonymous):

Does it give you any lengths for the triangle?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

@hartnn can you help?

OpenStudy (anonymous):

If tan x ̊= z divided by 10 and cos x ̊=10 divided by y ,what is the value of sin x°? sin x° = y over z sin x° = z over y sin x° = 10z sin x° = 10y .

OpenStudy (anonymous):

yes those are my answer choices how did you get them doe?

OpenStudy (anonymous):

common sense? the answer is believe is c.

OpenStudy (jdoe0001):

\(\bf tan(x^o)=\cfrac{z}{10}\implies \cfrac{opposite}{adjacent}\implies \cfrac{{\color{blue}{ b}}}{{\color{blue}{ a}}}\implies \cfrac{{\color{blue}{ b}}=z}{{\color{blue}{ a}}=10} \\ \quad \\ cos(x^o)=\cfrac{10}{y}\implies \cfrac{adjacent}{hypotenuse}\implies \cfrac{{\color{blue}{ a}}}{{\color{blue}{ c}}}\implies \cfrac{{\color{blue}{ a}}=10}{{\color{blue}{ c}}=y} \\ \quad \\ recall\implies sin(\theta)=\cfrac{opposite}{hypotenuse}\)

OpenStudy (anonymous):

i didn't want to know the answer i wanted to know how you get the answer i want to learn this stuff

OpenStudy (anonymous):

i'm so confused can you explain this for me in words so i can understand this better ? @jdoe0001

OpenStudy (jdoe0001):

OpenStudy (anonymous):
