Best ResponseYou've already chosen the best response.1this is trig. If you need a quick refresher, see https://www.khanacademy.org/math/geometry/right_triangles_topic/ccgeometrytrig/v/basictrigonometry

Best ResponseYou've already chosen the best response.0I do know that the tan function is opposite over adjacent. So then that'd put 33.8/57.6

Best ResponseYou've already chosen the best response.0Yes can u calculate its value

Best ResponseYou've already chosen the best response.0Don't you divide 33.8 into 57.6 and get 0.5868, but then you'd need to use something else which then confuses me.

Best ResponseYou've already chosen the best response.1you have tan x = 0.5868... use "inverse tan" or \( \tan^{1} \) key on 0.5868...

Best ResponseYou've already chosen the best response.0Would you type in: tan^1 and then 0.5868?

phi

Best ResponseYou've already chosen the best response.1On my calculator, I first type in the number then hit shift (or inverse) then tan (marked \(\tan^{1} \)

Best ResponseYou've already chosen the best response.0Oh, I forgot to tell you guys the answer choices: A) 30.4 B) 35.9 C) 54.1 D) 59.6

Best ResponseYou've already chosen the best response.1it will be obvious if you figure out how to use your calculator.

Best ResponseYou've already chosen the best response.0I'm trying to figure it out now. Just a second.

anonymous

Best ResponseYou've already chosen the best response.0So, I did like you said, I typed in the number (0.5868) and then I pressed shift and press tan^1, but it gave me an error?

anonymous

Best ResponseYou've already chosen the best response.0I did tan^1 and typed in the numbers as well, and it gave me: 0.5306

Best ResponseYou've already chosen the best response.1you are in radian mode. multiply by 180/pi or easier, change your mode to degrees

anonymous

Best ResponseYou've already chosen the best response.0How would I change the mode? The calculator I'm using is a Casio. Sorry if I'm making this challenging, I'd just like to understand the problem.

phi

Best ResponseYou've already chosen the best response.1I'm looking at the manual. meanwhile, to get the answer, multiply 0.5306*180/pi

Best ResponseYou've already chosen the best response.0Thank you for you help by the way, so I punched in what you told me to and I got: 30.416

phi

Best ResponseYou've already chosen the best response.1which rounds to 30.4º to change mode to "degrees" use shift menu (this gets you to "setup")

anonymous

Best ResponseYou've already chosen the best response.0Okay, I did that. Then what?

phi

Best ResponseYou've already chosen the best response.1you should see "angle" at the bottom scroll down using the "down cursor"

Best ResponseYou've already chosen the best response.0Yes, then press Execute?

phi

Best ResponseYou've already chosen the best response.1it says press function keys to change the setting?

phi

Best ResponseYou've already chosen the best response.1yes, execute, then F1 (I am guessing)

anonymous

Best ResponseYou've already chosen the best response.0Okay, I'll try it. Just a moment please.

anonymous

Best ResponseYou've already chosen the best response.0Hm, so I pressed execute then F1, it takes me to the Matrix suggestions. They're from AZ and then after Z is Mat Ans.

phi

Best ResponseYou've already chosen the best response.1were you on the "angle" line when you hit exe ?

phi

Best ResponseYou've already chosen the best response.1try again, just to be sure

anonymous

Best ResponseYou've already chosen the best response.0Okay, I'll tell you what I've been doing. I press the shift button and then press the Menu button but it takes me to the Set Up since that is for the shift button. Then I move downward to "Angle" and next to the word angle on the far right is the words: " :Rad" I then press Execute and go to F1, not using the shift bar or anything else.

phi

Best ResponseYou've already chosen the best response.1maybe once you are at the angle line, just press F1 ?

anonymous

Best ResponseYou've already chosen the best response.0It doesn't take me anywhere.

anonymous

Best ResponseYou've already chosen the best response.0Oh, yes it does. Once I pressed F1 it changed to Deg.

anonymous

Best ResponseYou've already chosen the best response.0Okay, then what next?

phi

Best ResponseYou've already chosen the best response.1check it works, try shift tan ( \(\tan^{1} \) ) 0.5868

anonymous

Best ResponseYou've already chosen the best response.0I typed in exactly what you told me to and I got: 30.4. So yes, it worked! I'm so happy. Thank you for helping me through this problem and fixing my calculator haha. You've been a great help!

phi

Best ResponseYou've already chosen the best response.1so what you did was tan x = 0.5868 then you did "inverse tan" of both sides \[ \tan^{1}\left( \tan x\right) = \tan^{1} 0.5868 \\ x= \tan^{1} 0.5868 \\ x= 30.4 \ degrees \]
