where is a Question.

OpenStudy (anonymous):

\[\tan(43)=\frac{6}{c}\] \[c=\frac{6}{\tan(43)}\] and a calculator

OpenStudy (anonymous):

So i just divide 43/6? @satellite73

OpenStudy (anonymous):

oh no

OpenStudy (anonymous):

it is six divided by the tangent of 43 degrees

OpenStudy (anonymous):

you need a calculator for this lets go slow tangent is "opposite over adjacent"

OpenStudy (anonymous):

in your picture the "opposite" side to the angle is 6 and the adjacent is \(c\) the number you are looking for

OpenStudy (anonymous):

that makes \[\large\tan(43)=\frac{6}{c}\] and we can solve this equation for \(c\)

OpenStudy (anonymous):

solving gives \[\large c=\frac{6}{\tan(43)}\]

OpenStudy (anonymous):

i get it now the answer to this question is A. 6.4 , can i do the same for this one

OpenStudy (anonymous):

and that you compute with a calculator

OpenStudy (anonymous):

yeah 6.4 is good

OpenStudy (anonymous):

this one is different you are looking for \(a\) which is the "opposite" side, and you know the hypotenuse you would use sine, since sine is opposite over hypotenuse

OpenStudy (anonymous):

\[\large \sin(43)=\frac{a}{6}\] is the first thing to write then solve for \(a\) and get \[a=6\times \sin(43)\] then use a calculator

OpenStudy (anonymous):

The answer is A. 4.09

OpenStudy (anonymous):

the answer is a number, not a letter

OpenStudy (anonymous):

oh yea, 4.09
