@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 ??

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 :)

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 = ...

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

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):
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 :)
