Best ResponseYou've already chosen the best response.0i understand everything except the red circle part.

Best ResponseYou've already chosen the best response.0oh yay astrophysics to the rescue <3

Astrophysics

Best ResponseYou've already chosen the best response.1It's a property that tells us this \[\huge \frac{ a }{ \frac{ b }{ c } } = \frac{ c \times a }{ b }\]

Best ResponseYou've already chosen the best response.1So think of it this way, dw:1436161113139:dw it's just dividing by fractions really

Astrophysics

Best ResponseYou've already chosen the best response.1Remember when you divide fractions, you take the second fraction, flip and multiply

Best ResponseYou've already chosen the best response.0what i'm asking is, shouldn't the entire part be,

Best ResponseYou've already chosen the best response.0\[\frac{ 10 }{ \tan(<BAC) }=\frac{ 10 }{ 9 }\]

Astrophysics

Best ResponseYou've already chosen the best response.1No because \[\tan(< BAC) = \frac{ 10 }{ 9 }\]

Best ResponseYou've already chosen the best response.0why is it like, how it's posted in the example.

Best ResponseYou've already chosen the best response.0my way leads to the answer being 9 though?

Best ResponseYou've already chosen the best response.1You're just plugging 10/9 for for that expression, that's all

Best ResponseYou've already chosen the best response.0what is that 10 then?

Mizuki

Best ResponseYou've already chosen the best response.1the 10 on the top of 10/tan(<BAC)

anonymous

Best ResponseYou've already chosen the best response.0you understand everything mizuki?

Astrophysics

Best ResponseYou've already chosen the best response.1BC = 10, because what you're solving for is AC, dw:1436161552377:dw

Best ResponseYou've already chosen the best response.0can't it be like this though,

Best ResponseYou've already chosen the best response.1No, because you're saying that tan(<BAC) = 9 then

Astrophysics

Best ResponseYou've already chosen the best response.1But it actually = 10/9

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1the 10 in the numerator represents BC

anonymous

Best ResponseYou've already chosen the best response.0ohhh and 10/9 is a ratio right?

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1Yes, that the tan ratio

anonymous

Best ResponseYou've already chosen the best response.0and you use that ratio to solve for the missing side (adjacent).

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1Yes, because they told you that tan(<BAC) = 10/9 (for the angle of triangle)

Astrophysics
 one year ago
Best ResponseYou've already chosen the best response.1But what you're looking for is the side AC
