@jim_thompson5910 A?? :)
jimthompson5910 (jim_thompson5910):
look at angle x, what is opposite of it?
OpenStudy (anonymous):
Y @jim_thompson5910

jimthompson5910 (jim_thompson5910):
which side is opposite angle x
OpenStudy (anonymous):
tan Y is the right answer @jim_thompson5910
jimthompson5910 (jim_thompson5910):
don't worry about the answer, what side is opposite angle x?
OpenStudy (anonymous):
side P
jimthompson5910 (jim_thompson5910):
what is the hypotenuse

Q
jimthompson5910 (jim_thompson5910):
what is sine (use the link I gave you)
jimthompson5910 (jim_thompson5910):
specifically what is sin(x)
OpenStudy (anonymous):
ohhh ok sine is opposite/hypotenuse
jimthompson5910 (jim_thompson5910):
yes

jimthompson5910 (jim_thompson5910):
so because the opposite of angle x is p
and the hypotenuse is q
this means
sin(x) = p/q
jimthompson5910 (jim_thompson5910):
but we want r/q, so sin(x) can't be the answer
OpenStudy (anonymous):
cosineX because opposite of x is R and adjacent of x is Q :)
jimthompson5910 (jim_thompson5910):
cos isn't opp/hyp though
jimthompson5910 (jim_thompson5910):
I think you meant to say adjacent is r

aaahh oopp my bad
jimthompson5910 (jim_thompson5910):
cosine is what?
jimthompson5910 (jim_thompson5910):
use the link again
OpenStudy (anonymous):
yea im sorry ok i will give me a sec to clearly look at it
jimthompson5910 (jim_thompson5910):
its ok

ok lol so adjacent/hypotenuse is what i meant to say because that's cosine so Cos x
jimthompson5910 (jim_thompson5910):
good, cos = adj/hyp
jimthompson5910 (jim_thompson5910):
so what is cos(x)
OpenStudy (anonymous):
wow that was a really easy problem but i was making stupid mistakes but thanks
jimthompson5910 (jim_thompson5910):
that's ok

cos(x) is adjacent/hypotenuse
jimthompson5910 (jim_thompson5910):
what's the adjacent side to angle x
OpenStudy (anonymous):
r
jimthompson5910 (jim_thompson5910):
what's the hypotenuse
