Question

Find the values of w and then x. Round lengths to the nearest tenth and angle measures to the nearest degree.

Answer 1

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

Answer 2

i had to take a break my brain was smoking

Answer 3

sin30= w/6. get w.

Answer 4

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

Answer 5

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

Answer 6

cosx=w/4**

Answer 7

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

Answer 8

Good job.

Answer 9

@nincompoop i am using SOH CAH TOA :D

Answer 10

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

Answer 11

what is that symbol ^^

Answer 12

sorry, \(\large \theta = x\).

So \[\large \cos(x) = \frac{3}{4}\]\[\large x = \cos^{-1} \left(\frac{3}{4}\right)\]

Answer 13

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

Answer 14

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

Answer 15

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

Answer 16

41.4=x

Answer 17

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

Answer 18

ty :DD ima fast learner

Answer 19

@katherine.ok @nincompoop @Jhannybean thanks for the help

Answer 20

No problem.
