Find the value of x..

OpenStudy (anonymous):

Where?

OpenStudy (anonymous):

|dw:1336076694437:dw|

OpenStudy (anonymous):

there

OpenStudy (anonymous):

use sin. \[\LARGE \sin 60^{\circ}=\frac{x}{14} \]

OpenStudy (anonymous):

@Kreshnik it gave me 0.86

OpenStudy (anonymous):

well that's not what I just came up with... \[\LARGE \sin 60^{\circ}=\frac{\sqrt3}{2}\]

OpenStudy (anonymous):

and you have: \[\LARGE \frac{\sqrt3}{2}=\frac{x}{14}\] continue.. see what you get.

OpenStudy (anonymous):

i didnt get that/:

OpenStudy (anonymous):

what don't you get?

OpenStudy (anonymous):

the answer.. i got 3.24

OpenStudy (anonymous):

do you mind showing steps...

OpenStudy (anonymous):

its on the caculator i think im doing it wrong

OpenStudy (anonymous):

can you do it without calculator?

OpenStudy (anonymous):

you know the answer to that lol

OpenStudy (anonymous):

where are you stuck?

OpenStudy (anonymous):

the answer .

OpenStudy (anonymous):

\[\LARGE \frac{\sqrt3}{2}=\frac{x}{14}\] use cross multiply, and tell me what you get

OpenStudy (anonymous):

/:

OpenStudy (anonymous):

can't you do that? \[\LARGE 14\sqrt3=2x \] now divide both sides by 2. and tell me what you get.

OpenStudy (anonymous):

24.2

OpenStudy (anonymous):

3.24

OpenStudy (anonymous):

?

OpenStudy (anonymous):

24.2 =what? 3.14=what? 24.2=x 24.2=2x 24.2=3x ... 24.2=100x ? :) which one you mean?

OpenStudy (anonymous):

3.24 ... IDK im confused

OpenStudy (anonymous):

did you use calculator? (I can give you the answer but you should know how to do it)

OpenStudy (anonymous):

Yeah, and you should and explain how you got it that way ill still learn it

OpenStudy (anonymous):

1. I explained everything it could be explained so far, is just that I think you're still not capable to solve these . 2. don't use calculator 3. try dividing it again. 4.here's another hint: \[\LARGE \frac{14\sqrt3}{2}=\frac{2x}{2}\] 5. simplify 6.tell me what you get :)

OpenStudy (anonymous):

12.12?

OpenStudy (anonymous):

yes that's correct. well done. :) x\(\approx \)12.12

OpenStudy (anonymous):
