Best ResponseYou've already chosen the best response.1i understand everything except the red circle part.

Best ResponseYou've already chosen the best response.1oh yay astrophysics to the rescue <3

Astrophysics

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

Astrophysics

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.1nono i know this already.

Best ResponseYou've already chosen the best response.1\[\frac{ 10 }{ \tan(<BAC) }=\frac{ 10 }{ 9 }\]

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

Best ResponseYou've already chosen the best response.1why is it like, how it's posted in the example.

Best ResponseYou've already chosen the best response.1my way leads to the answer being 9 though?

Best ResponseYou've already chosen the best response.1wait i get it a little!

Astrophysics

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.1what is that 10 then?

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

mindblast3r

Best ResponseYou've already chosen the best response.1you understand everything mizuki?

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

mindblast3r

Best ResponseYou've already chosen the best response.1can't it be like this though,

Mizuki

Best ResponseYou've already chosen the best response.1yes i do understand everything @Mindblast3r

Best ResponseYou've already chosen the best response.1dw:1436161657752:dw

Astrophysics

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

Astrophysics
 one year ago
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

mindblast3r

Best ResponseYou've already chosen the best response.1ohhh and 10/9 is a ratio right?

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

mindblast3r
 one year ago
Best ResponseYou've already chosen the best response.1and 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
