am i right with D?

@laylalyssa

Arieonna:

ask her she is good with math

dancingwiththereaper:

Ay what grade is this for? I used to be really good at geometry

Gucchi:

9th

dancingwiththereaper:

One moment please

dancingwiththereaper:

Is this in like a specific topic?

dancingwiththereaper:

Also is there a time limit?

specific right triagnles

dancingwiththereaper:

Give me like 5 ish minutes?

jhonyy9:

to get AB use tg45 to get AG subtract from BG the AB and now to get EA use cos60

dancingwiththereaper:

@jhonyy9 Are you sure that is right?

jhonyy9:

yes of cours

dancingwiththereaper:

I wasn't talking crap I was just asking if u were sure that was right

dancingwiththereaper:

I honestly don't know what the right answer was I was getting on with a tutor to get the answer tbh XD

jhonyy9:

tg45 = 64/AB sqrt2 / 2 = 64 / AB AB = ? 137 - AB = AG cos60 = AG / EA EA = AG / cos60

Looks good to me

okay yeah the answer is D then

Gucchi:

wait AB is 45

idk i dont made the calcules just gave the way to solve it

dancingwiththereaper:

I can check the answer if y'all want i'm on with a tutor right now

Gucchi:

yes get it please

Almost done

idk im still really confused by this

dancingwiththereaper:

Just give me a few more minutes I am working as fast as I can

Gucchi:

okay i dont think its D

dancingwiththereaper:

73 square root of 3!!

dancingwiththereaper:

Option b

Gucchi:

can u give an explanation rq

dancingwiththereaper:

Hope it explains it

Gucchi:

@jhonyy9 do u agree with 73?

Gucchi:

you could have done cos(60)=EA/AG right?

dancingwiththereaper:

yeah

Gucchi:

Well if you calculate h it will be 73×2=146 which is correct but you could have directly done AE=AG/cos60, no?

dancingwiththereaper:

I'm pretty sure yeah

Gucchi:

okay okay so 73 makes sense then

Gucchi:

did you draw that or a tutor?>

dancingwiththereaper:

I drew some of it and the tutor drew some of it

Yes, either way it would be the same thing

dancingwiththereaper:

^both ways are correct

Gucchi:

no so it should be C

Gucchi:

146 right?

dancingwiththereaper:

No it should be 73 square root of 3

dancingwiththereaper:

I may be wrong

Gucchi:

but 73*2 = 146 right??

dancingwiththereaper:

yes

dancingwiththereaper:

That is correct

Gucchi:

alright thank yiu

dancingwiththereaper:

no problem!

dancingwiththereaper:

Hope it helps!
