@hartnn

hartnn (hartnn):

angle = 30 opposite side to 30 is ??

hartnn (hartnn):

adjacent side is ?? hypotenuse is ??

OpenStudy (anonymous):

y opposite x hypotenuse 16sqrt3 adjacent

hartnn (hartnn):

opposite side = y is correct hypotenuse is the longest side! which is opposite to 90 degree angle

hartnn (hartnn):

|dw:1398505639625:dw|

hartnn (hartnn):

so again adjacent side is ?? hypotenuse is ??

OpenStudy (anonymous):

Ohhh that's why i kept getting it wrong last time and I was so confused she didn't explain that

hartnn (hartnn):

now you know :)

OpenStudy (anonymous):

Ok so adjacent is x and 16sqrt3 is hypotenuse

hartnn (hartnn):

correct :) now sin 30 = opposite side/ hypotenuse sin 30 = ... / ... ???

OpenStudy (anonymous):

y/16sqrt13

OpenStudy (anonymous):

lol @meshlogic it was an easy mistake to make but you were right

hartnn (hartnn):

yeah, and sin 30 = 1/2 so. y= 16 sqrt 3 /2 = ...

OpenStudy (anonymous):

13.856

hartnn (hartnn):

correct :)

OpenStudy (anonymous):

so now what ?

hartnn (hartnn):

cos 30 = ...?

OpenStudy (anonymous):

x/16sqrt3

OpenStudy (anonymous):

cos 30 = .866

hartnn (hartnn):

correct

hartnn (hartnn):

so whats the value of y ?

OpenStudy (anonymous):

you mean x ?

hartnn (hartnn):

yes

OpenStudy (anonymous):

ok umm 24!

hartnn (hartnn):

good! :)

OpenStudy (anonymous):

and y= 8sqrt 3 right ?

hartnn (hartnn):

yes, it is :)

OpenStudy (anonymous):

omg ! thank you so much @hartnn and @meshlogic ^_^

OpenStudy (anonymous):

I suck at geometry lol I needed this help and no i'm not

OpenStudy (anonymous):

It's cool my mistake

OpenStudy (anonymous):

I did

hartnn (hartnn):

lol, i am not gonna get to 100 in years! plus i don't care for medals anymore.... you understand, thats my reward :)

OpenStudy (anonymous):

Yaaaaaaaay! You did it! Lol
