Question

Can someone check my answer? I think I got it but I haven't done math in a bit. Thanks :)

Answer 1

@mathmale

Answer 2

Yeah that's right. You took the arc cos of 6/11 right?

Answer 3

Answer 4

very funny ms.brains. thank you both :)

Answer 5

yeah. nice tabs LOL

Answer 6

Welcome! :)

Answer 7

may I have some more help? Im a little confused on the next one... and (shhhhh I love listening to music while I work)

Answer 8

yeah sure. and no criticism here, music helps a ton lol. theres no way i'd be far into my calc homework without musicz :P

Answer 9

:P thanks lol one is my work and the other is the question

Answer 10

:/ or is it supposed to be this?

Answer 11

It's tan(68*) = 14/x

Answer 12

This is due to TOA = Tangent = Opposite/Adjacent

Answer 13

I think it's the last one. If i recall elevation is that and depression is the other?

Answer 14

Yeah what king said. So then just solve for x :p

Answer 15

Yes, then just do 14/tan(68*) to get your answer.

Answer 16

^^^^^

Answer 17

Even after looking at your illustration several times, I'm still unsure which angle is 68 degrees. You seem to be presenting two options. One acute angle is 68; the other option is the other acute angle is 68 deg. Mind going back to the wording of the original problem and sharing it as is?

Answer 18

I did.

Answer 19

I said "one is the question and one is my work"

Answer 20

and I did both :/ im not getting either of those answers.

Answer 21

It got cut off :/ The part after the ='s is supposed to be 14 at the top.

Answer 22

In the end the ultimate authority on what was meant is the original question. Would you mind sharing that original question one one manner or another (a screen shot would be most appreciated), including any and all descriptions and/or instructions?

Answer 23

This is the original question she sent: http://assets.openstudy.com/updates/attachments/5711a777e4b09810852d2f1d-rhondasommer-1460775916122-screenshot179.png

Answer 24

Actually wait up. If you do it the other way where tan 68 = x/14 that appears to be one of the choices.

Answer 25

solving for x of that anyway

Answer 26

So maybe the first illustration of that angle was the correct way?

Answer 28

thanks, King. Then the 68 degree angle, the angle of elevation, is the one adjacent to the horizontal axis. I believe we are assuming here that the top of the laddeer exactly touches the top of the 14-foot wall.

If these assumptions are correct (and that's a big IF), then 14 is the opposite side to 68 degrees, x is the adjacent side, and tan 68 degrees = 14/x.

Answer 29

^ And he's just trying to help even if you did mention it already :O

Answer 30

sorry, im getting frustrated at the question 6-6 my bad

Answer 31

Alternatively, trying them both ways and comparing the answers would tell you which placement of the angle is correct, but that leads to problems if the answers included both placements which in this case luckily didn't. :P

Answer 32

urg. IM SO CUNFUZZLED

Answer 33

ok just ignore me listen to mathmale lol.

Answer 34

Focus on "angle of elevation" for a moment. This is the key to which angle is the one in questin. Suppose you happen to be lying on your stomach on the grass and look at a balloon in the air above you and some distance downwind from you. That's your angle of elevation. The opposite would be the angle of depression, which does not apply here. Therefore, one of your drawings must be thrown out the window, so to speak. Which one?

Answer 35

tan68 = 2.47508685
2.47508685 = 14/x but but
i get - 0.17679191785714285714285714285714
AND THATS NOT ONE OF MY CHOICES

Answer 36

not negative; it was meant to be - (this is what it is)

Answer 37

Please go back to the illustration that correctly reflects "angle of elevation is 68 degrees." Only one of your illustrations is correct. Which one?
Copy that drawing and submit it again here.

Answer 38

no. im aware of what the equation is now. im not going back to step one -_-

Answer 39

As you wish.

Answer 40

my problem is im not getting any of the answers that they are proposing
