OpenStudy (anonymous):

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

ok..lemme try

OpenStudy (anonymous):

lol x,y and z

OpenStudy (anonymous):

trigonometry should easily do this..:)

OpenStudy (anonymous):

so what are they lol

OpenStudy (anonymous):

cos 45=x/12 ,sin 60=12/z

OpenStudy (anonymous):

WHAT hahaha

OpenStudy (anonymous):

you didnt get that??

OpenStudy (anonymous):

ya but they came out to really weird numbers

OpenStudy (anonymous):

it will be weird :) math is weird

OpenStudy (anonymous):

x=6 root 2?

OpenStudy (anonymous):

so is x 8.4?

OpenStudy (anonymous):

ya approximately

OpenStudy (anonymous):

ok:) what about Y

OpenStudy (anonymous):

use trig ratios

OpenStudy (anonymous):

we might wanna find z first

OpenStudy (anonymous):

wait but is it 8.48 or just8.4

OpenStudy (anonymous):

sin 60=12/z

OpenStudy (anonymous):

for example x/12 = cos45 or x= 12*cos45 =12/sqrt(2) ....

OpenStudy (anonymous):

?

OpenStudy (anonymous):

z=2 root 3

OpenStudy (anonymous):

approximately 3.5

OpenStudy (anonymous):

z is 3.46 ya

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

cos 60=y/3.46

OpenStudy (anonymous):

ok now y ;p

OpenStudy (anonymous):

umm I got 0.14 but I think that's wrong

OpenStudy (anonymous):

y=3.46/2

OpenStudy (anonymous):

1.73?

OpenStudy (anonymous):

1.73=y

OpenStudy (anonymous):
