Do you understand this??
mayankdevnani
  • mayankdevnani
|dw:1371537210091:dw| what are these???
anonymous

i dont know. thats what im trying to figure out. Thats what it looks like on my quiz though.
mayankdevnani

Ohh..i see. But then what is x &? i dont know how to get it.

\[\huge if ~x~degree=2x-13\] \[\huge so~what~is~the~value~of~y???\]

y= 3 ?
mayankdevnani
  • mayankdevnani
no!!!

2x-13=x-3 ?
anonymous
  • anonymous
i have less then 2 minutes to solve this equation. Do you think you could give me the answer and then explain it?
ganeshie8
  • ganeshie8
lets start it over
anonymous
  • anonymous
i have less then 2 minutes.. but sure.
ganeshie8
  • ganeshie8
|dw:1371537873355:dw|
ganeshie8
  • ganeshie8
2x-3 and x-3 are sides. they are not angles.
anonymous
  • anonymous
ok.
mayankdevnani
  • mayankdevnani
|dw:1371537894805:dw| right?? @ashleyvee
anonymous
  • anonymous
right.
ganeshie8
  • ganeshie8
First get this clear, 2x-13 and x-3 are sides, they are not angles.
anonymous
  • anonymous
ok.
ganeshie8
  • ganeshie8
then everything else is simple and easy
ganeshie8
  • ganeshie8
Good, lets start from there
anonymous
  • anonymous
ok
ganeshie8
  • ganeshie8
in isosceles trap, sides are equal.
ganeshie8
  • ganeshie8
set them equal, and solve x
mayankdevnani
  • mayankdevnani
|dw:1371537984499:dw| @ganeshie8
anonymous
  • anonymous
y?
ganeshie8
  • ganeshie8
mayank il get back to u ltr, is that fine ?
mayankdevnani
  • mayankdevnani
first tell me
ganeshie8
  • ganeshie8
lets go step by step, first solve x
ganeshie8
  • ganeshie8
2x-13 = x-3 solve x
anonymous
  • anonymous
i have less then 60 seconds for this problem. D:
anonymous
  • anonymous
Can you just give me the answer and expl after?
mayankdevnani
  • mayankdevnani
oh!! i see ..... @ashleyvee you diagram was incorrect
ganeshie8
  • ganeshie8
we're going to finish it in less than 60 seconds
ganeshie8
  • ganeshie8
x = 10
mayankdevnani
  • mayankdevnani
your diagram will look like this: |dw:1371538145453:dw|
anonymous
  • anonymous
i ran out of time.. :/
anonymous
  • anonymous
so y= 46 or 44?
mayankdevnani
  • mayankdevnani
solve it @ashleyvee \[\huge 2x-13=x-3\] solve for x???
ganeshie8
  • ganeshie8
thats right ! B. x = 10, y= 46
ganeshie8
  • ganeshie8
ashley sorry you ran out of time :(
anonymous
  • anonymous
x=10
anonymous
  • anonymous
its okay. i have to retake it now. so at least i have another 50 minutes for the answer x)
ganeshie8
  • ganeshie8
each questio u take it separately is it ?
ganeshie8
  • ganeshie8
or u lost the whole assignment ?
anonymous
  • anonymous
i get 10 questions and about an hour to finish it. I absolutely hate that its timed. :/
anonymous
  • anonymous
i failed the assignment with a 40% xD
ganeshie8
  • ganeshie8
its okay, you will do super fine next time
anonymous
  • anonymous
opposite angles are equal and a pair of opposite sides are equal. 2x-13=x-3, 3y-4=y =>x=10. and y=2
anonymous
  • anonymous
i get two more times to retake it before i receive an F for the assignment. These problems are getting so tricky though. :/ its taking me longer then an hour to do them. xD
anonymous
  • anonymous
y is actually 46. if it were 2 then x would equal 8. o:
ganeshie8
  • ganeshie8
lets do it 100m dash next time :)
ganeshie8
  • ganeshie8
yes y = 46 is correct
anonymous
  • anonymous
haha yeah! x) at least i can study for a few before i retake. o:
ganeshie8
  • ganeshie8
sounds good :D
anonymous
  • anonymous
i'm again sorry
ganeshie8
  • ganeshie8
Abhishek let ashlee solve it :)
anonymous
  • anonymous
ganeshie you shall receive best responce! x) again. hah
ganeshie8
  • ganeshie8
lol ty
anonymous
  • anonymous
good ashleyvee. try to solve it. you are getting it.
anonymous
  • anonymous
thanks abhishek but the answer was actually C. o:
anonymous
  • anonymous
Do you guys think you can help me with another equation i got wrong?
ganeshie8
  • ganeshie8
uhh C ?
anonymous
  • anonymous
i meant B. x)
ganeshie8
  • ganeshie8
C means B, ok fine il use it next time xD
ganeshie8
  • ganeshie8
yea, post the q...
anonymous
  • anonymous
sure.
anonymous
  • anonymous
lol okie doke. This ones really...difficult. :/

ganeshie8
  • ganeshie8
thats a lil parallelogram
anonymous
  • anonymous
Parallelogram QRST is shown. m
anonymous
  • anonymous
But its the equation that getting me. D: im so confused!!
ganeshie8
  • ganeshie8
S, R and Q are given
mayankdevnani
  • mayankdevnani
|dw:1371539009137:dw| opposite angles of parallelogram are equal
mayankdevnani
  • mayankdevnani
so, \[\huge 3x=2y\]
anonymous
  • anonymous
A.20 B.30 C.40 D.60 Its not C for sure.
ganeshie8
  • ganeshie8
use this :- 120 + 2y = 180
ganeshie8
  • ganeshie8
solve y
anonymous
  • anonymous
y=30 !!
ganeshie8
  • ganeshie8
Yes ! u take any two adjacent angles, they always add up to 180
mayankdevnani
  • mayankdevnani
to find the value of x, |dw:1371539100093:dw| they form a straight angle so \[\huge 3x+120=180\] solve for x??? @ashleyvee
anonymous
  • anonymous
x=20!
mayankdevnani
  • mayankdevnani
correct
anonymous
  • anonymous
i get problems like this. its just when they throw a shape in there i get confused. :/ oh boy.
mayankdevnani
  • mayankdevnani
so opposite sides of parallellogram are equal... \[\huge 3x=2y\] \[\huge 3 \times 20=2y\] solve for y??? @ashleyvee
anonymous
  • anonymous
y=30
ganeshie8
  • ganeshie8
they will be mostly throwing u shapes that fall into one of below :- 1. parallelogram 2. rectangle 3. rhombus 4. square 5. kite 6. trap
mayankdevnani
  • mayankdevnani
correct
mayankdevnani
  • mayankdevnani
so correct option is B
ganeshie8
  • ganeshie8
Only those 6 shapes you need to master in geometry
anonymous
  • anonymous
Theyve been throwing all of those at me. x)
ganeshie8
  • ganeshie8
lol
anonymous
  • anonymous
I think ive mastered the square...lol
ganeshie8
  • ganeshie8
square is the simplest of them :)
ganeshie8
  • ganeshie8
master parallelogram also, it comes everywhere
anonymous
  • anonymous
i have another parallelogram question now that i got incorrect. xD
ganeshie8
  • ganeshie8
shoot
mayankdevnani
  • mayankdevnani
post it
anonymous
  • anonymous
okay. ill draw it first!
mayankdevnani
  • mayankdevnani
great
ganeshie8
  • ganeshie8
ha

In parallelogram MATH, m
anonymous
  • anonymous
@.@ ... asdfghjkl. 3x+20=5x-4? D: ?
ganeshie8
  • ganeshie8
yes thats a good start
ganeshie8
  • ganeshie8
solve x first
anonymous
  • anonymous
how do i cancel out? the x first right?
anonymous
  • anonymous
or wait.. do i add those numbers?
ganeshie8
  • ganeshie8
3x+20=5x-4 subtract 3x both sides
ganeshie8
  • ganeshie8
3x+20=5x-4 -3x -3x
anonymous
  • anonymous
3x+20=5x-4 -3 -3 ______________ 20=2x-4
ganeshie8
  • ganeshie8
add 4 both sides
anonymous
  • anonymous
20=2x-4 4 4 __________ 24=2x -- -- 2 x 2x
anonymous
  • anonymous
x=12 ?
ganeshie8
  • ganeshie8
yes
anonymous
  • anonymous
Now what?
ganeshie8
  • ganeshie8
|dw:1371539975918:dw|
ganeshie8
  • ganeshie8
read the q once, we need to find
anonymous
  • anonymous
56?
anonymous
  • anonymous
or 112?
ganeshie8
  • ganeshie8
56 is
anonymous
  • anonymous
so it should be 56 right? and not 112?
ganeshie8
  • ganeshie8
so now we knw
anonymous
  • anonymous
i got something like 56+56=112 but i also got just 56 without adding.
anonymous
  • anonymous
Do we find a by adding 56^2?
ganeshie8
  • ganeshie8
use this :- in parallelogram, any two adjacent angles add upto 180
anonymous
  • anonymous
oops not squared. i meant 56 x 2= 112
ganeshie8
  • ganeshie8
|dw:1371540189544:dw|
anonymous
  • anonymous
56+x=180 ?
ganeshie8
  • ganeshie8
56 + A = 180 A = ?
anonymous
  • anonymous
124?
ganeshie8
  • ganeshie8
Yes.
ganeshie8
  • ganeshie8
remember that property
anonymous
  • anonymous
:D yes!! thank you!! i keep forgetting.. :/ But i can try.
ganeshie8
  • ganeshie8
in parallelogram, Any two adjacent angles add upto 180
ganeshie8
  • ganeshie8
no try not, there is no try. remember it lol
anonymous
  • anonymous
ive tried for over 4 years.. x) it just never sticks. Im a very forgetful person. :(
ganeshie8
  • ganeshie8
u watched any eposodes of starwars
anonymous
  • anonymous
hahahah. Nope. why?
ganeshie8
  • ganeshie8
ok... nthng move on :)
