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

@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

okay yeah the answer is D then
Gucchi:
wait AB is 45

okay i dont think its D
dancingwiththereaper:
73 square root of 3!!
dancingwiththereaper:
Option b
Gucchi:
can u give an explanation rq
dancingwiththereaper:
Here u go!

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:

dancingwiththereaper:
That is correct
Gucchi:
