alright
alr i'm here
trapezium
trapezium
what language is that?
and rhombus
yee I'm looking at the problems
i have a national exam to get into university i started learning math this year
it might look easy to u guys but my whole country struggling on this sh
this is just the beginning of geometry too
trapezoid one first question answer is 90
which ones do you not know
kind of yeah
alr imma look at 6
listen
quick summary
i study math at a teacher
im just tryna learn more at home
because i need to get good enough at math in 3 months to pass the exam
oh alr
alr in Q6 the trapezium is isoceles
isoceles?
so you can use congruency and some simple algebra to get the answer a 14
what ๐ ๐ญ
non parallel sides are equal in length
This is gonna take a diagram isn't it...
oh lol
7th one you'll get 4 as the answer
same logic
wait so how do u solve 6
well as the thing is an equal side uh thing
you'll get the result that the cutoffs of the base on the sides of the altitudes are equal
ok label the points where the altitudes touch ad E and F
no problem bro
ok so look @shadow plume
what do i do
to find X
bruh
i get it
its 14
๐คฃ
draw the other altitude and label all the points
alr
ill just try to solve all of them, and ill be texting them here while i get stuck
thanks for help tho
alr
such a nice community
7th its the same logic
bless u bro
you're welcome lol
the eighth one is tricky- took me a few seconds to get it
but yeah you should be able to do it (hint is angle chasing)
correct?
X is the whole base right
so i gotta add them all up
@shadow plume
this ones confusing
8th
x is not the whole base
x+y is the whole base
so its 6?
try angle chasing
is X 8 or 6
6
find all the angles
its fine
OH
prove that
oof
yes lol
oh
i get it now
and the other sides 6 too
since its equal
so the base is 10
is it
actually
not 10
9
wait
i dont even need to find hte base
X is 6
9th
which question?
yes correct
its so easy
yeah geometry is like that
once you get the hang of it you can breeze through it no sweat lol
its just that
when doing tests
alot of new shit show up right after the other
so i awlays need to wait for the teacher to come to me and explain
oh oof
studying like this is kinda faster tbh
yeah just breeze through and then when you reach a roadblock then you ask for help
oh- I may or may not do college math for fun sooooo
I enjoy it lol
when u enjhoy something its easier to do
forcing urself to do something makes it harder
if i coudl dedicate the same amount of time i dedicate to gym and gaming to math without getting bored id be very good at it too
yeah true
ppl have different interests
i do not know trigonometry at all
do you know trigonometry-
oof-
๐คฃ
that complicates things
theres an alternate way without trigonometry
but it's much longer
which is
constructions and lots of algebra
ok what i did is 27 - 2*10*cos(60)
yes
yeah lol
lmao
cos(60) is 1/2 so yeah
yep
oh
i did a little bit of thos
cos
tang
cotang
and shit
yes
ok so perimeter is 18
no
22
how
you'll get the sides of the trapezium as 4
(unfortunately using trigonometry)
9-5?
is that the trigonometry
lmao
is the sides 4 because of 9-5
or what
no problem
$\frac{9-5}2 \sec(60)$
No Lifer#GTFOanemia
๐
this is what the actual thing is like
Oh ok
I memorised only sin
nothing else lol
well if you're comfortable doing super quick calculations then that's all u need
didn't we alr solve this one?
is X 6
or 4
its either 6 or 4
let me try
nah i messed something up
it cant be this much
or is it right
no you messed up
OK what do i do
(10-4)/2 lol
yep
this one you have to do angle chasing
like find as many angles as possible
let me try
alr
angle BCD = 180 - 64
where do u get 32 from
the triangle up top is isoceles
you'll get 32 as (180-(180-64))/2
yeah try
this one the only option that makes sense is x=140
I can't justify it though...
Alr i have to leave now
You're welcome lol
