Can someone help

left crescent Apr 3, 2023, 5:03 PM

#

you need to

#

deconstruct the triangle

shy fiber Apr 3, 2023, 5:03 PM

#

i did do that but i am getting the wrong answer even by doing so

left crescent Apr 3, 2023, 5:03 PM

#

break them into 3 separate triangles

#

let me draw it out

shy fiber Apr 3, 2023, 5:04 PM

#

thank you

left crescent Apr 3, 2023, 5:06 PM

#

Triangle would appear like this

#

Happy?

#

shy fiber Apr 3, 2023, 5:06 PM

#

okay yes

left crescent Apr 3, 2023, 5:06 PM

#

you'd then work out the length of DB on this triangle.

shy fiber Apr 3, 2023, 5:06 PM

#

thank you

left crescent Apr 3, 2023, 5:06 PM

#

#

that's basically SOH CAH TOA

#

then once you work out DB, it's common to our other triangle

#

as they're the same length

#

then you'd just use SOH CAH TOA again to work out AD.

shy fiber Apr 3, 2023, 5:07 PM

#

thank you so much

left crescent Apr 3, 2023, 5:07 PM

#

no problem tell me if you dont get the right solution

shy fiber Apr 3, 2023, 5:07 PM

#

alright will do thank you

#

i am not getting the right answer

left crescent Apr 3, 2023, 5:14 PM

#

what did you get for

#

DB?

shy fiber Apr 3, 2023, 5:14 PM

#

73.35

#

oh wait

left crescent Apr 3, 2023, 5:14 PM

#

How?

shy fiber Apr 3, 2023, 5:14 PM

#

for DB

left crescent Apr 3, 2023, 5:14 PM

#

yeah

shy fiber Apr 3, 2023, 5:14 PM

#

i thought you meant for AD

left crescent Apr 3, 2023, 5:15 PM

#

its fine what did you get for

#

DB

shy fiber Apr 3, 2023, 5:15 PM

#

37.35

#

i used tan

left crescent Apr 3, 2023, 5:16 PM

#

ermmm

#

i agree, we'd use tan as we're looking for the adjacent

#

and we know the opposite

#

so it'd be

#

O/tan(theta)

#

so

#

46/tan(39)

shy fiber Apr 3, 2023, 5:17 PM

#

Oh you divide it

left crescent Apr 3, 2023, 5:17 PM

#

yeah, draw out the little triangles it always works a treat

shy fiber Apr 3, 2023, 5:18 PM

#

i got 56.81 now

#

for

#

DB

left crescent Apr 3, 2023, 5:18 PM

#

yeah im happy with that

#

got the same,

#

now just recalculate DB

shy fiber Apr 3, 2023, 5:18 PM

#

okay

#

and then you should be able to AD now

#

find

#

^^

left crescent Apr 3, 2023, 5:19 PM

#

yeah

#

you messed up the first bit, so obviously the second part wouldn't be correct

shy fiber Apr 3, 2023, 5:20 PM

#

is 73.1 AD?

#

that’s what i got

left crescent Apr 3, 2023, 5:20 PM

#

yeah

#

i agree

shy fiber Apr 3, 2023, 5:20 PM

#

Alright

#

Thanks so much

#

#

not sure how

left crescent Apr 3, 2023, 5:25 PM

#

try

#

73.35

shy fiber Apr 3, 2023, 5:28 PM

#

#

cheers bro

#

is it possible to help me with the other question i posted

#

i’ll tag you in it if you want

left crescent Apr 3, 2023, 5:29 PM

#
