Lol. you are still doing your math homework i see! Do you remember me?

i had to take a break my brain was smoking

sin30= w/6. get w.

lol hi @nincompoop and @katherine.ok yes i remember

Knowing w now, you now know that cos x=4/w. you know w, get x.

cosx=w/4**

ok \[\sin (30)=\frac{ w }{ 6 }\]
\[(6)*\sin 30=\frac{ w }{ 6 }*6\]
\[6\sin 30=w \]
w=3

Good job.

@nincompoop i am using SOH CAH TOA :D

Now that you found w, use \(\large \cos(\theta) = \frac{w}{4}\)

what is that symbol ^^

\[\cos (x)=\frac{ 3 }{ 4 }\]

\(\large \theta\) = theta, it signifies an angle measurement.

if cos x= 3/4 , punch in your calculator arccos(3/4) or equivalently, cos^-1(3/4)

41.4=x

arccos or cos^-1 is a function which returns degree or radians to fulfill the cos ratio. good job.

ty :DD ima fast learner

No problem.
