answers: A. x = 4, y= 2 B. x = 10, y= 46 C. x = 8,y = 2 D. x = 10, y= 44
Do you understand this??
|dw:1371537210091:dw| what are these???
i dont know. thats what im trying to figure out. Thats what it looks like on my quiz though.
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 ?
i have less then 2 minutes to solve this equation. Do you think you could give me the answer and then explain it?
lets start it over
i have less then 2 minutes.. but sure.
2x-3 and x-3 are sides. they are not angles.
|dw:1371537894805:dw| right?? @ashleyvee
First get this clear, 2x-13 and x-3 are sides, they are not angles.
then everything else is simple and easy
Good, lets start from there
in isosceles trap, sides are equal.
set them equal, and solve x
mayank il get back to u ltr, is that fine ?
first tell me
lets go step by step, first solve x
2x-13 = x-3 solve x
i have less then 60 seconds for this problem. D:
Can you just give me the answer and expl after?
oh!! i see ..... @ashleyvee you diagram was incorrect
we're going to finish it in less than 60 seconds
x = 10
your diagram will look like this: |dw:1371538145453:dw|
i ran out of time.. :/
so y= 46 or 44?
solve it @ashleyvee \[\huge 2x-13=x-3\] solve for x???
thats right ! B. x = 10, y= 46
ashley sorry you ran out of time :(
its okay. i have to retake it now. so at least i have another 50 minutes for the answer x)
each questio u take it separately is it ?
or u lost the whole assignment ?
i get 10 questions and about an hour to finish it. I absolutely hate that its timed. :/
i failed the assignment with a 40% xD
its okay, you will do super fine next time
opposite angles are equal and a pair of opposite sides are equal. 2x-13=x-3, 3y-4=y =>x=10. and y=2
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
y is actually 46. if it were 2 then x would equal 8. o:
lets do it 100m dash next time :)
yes y = 46 is correct
haha yeah! x) at least i can study for a few before i retake. o:
sounds good :D
i'm again sorry
Abhishek let ashlee solve it :)
ganeshie you shall receive best responce! x) again. hah
good ashleyvee. try to solve it. you are getting it.
thanks abhishek but the answer was actually C. o:
Do you guys think you can help me with another equation i got wrong?
uhh C ?
i meant B. x)
C means B, ok fine il use it next time xD
yea, post the q...
lol okie doke. This ones really...difficult. :/
thats a lil parallelogram
Parallelogram QRST is shown. m
But its the equation that getting me. D: im so confused!!
S, R and Q are given
|dw:1371539009137:dw| opposite angles of parallelogram are equal
so, \[\huge 3x=2y\]
A.20 B.30 C.40 D.60 Its not C for sure.
use this :- 120 + 2y = 180
Yes ! u take any two adjacent angles, they always add up to 180
to find the value of x, |dw:1371539100093:dw| they form a straight angle so \[\huge 3x+120=180\] solve for x??? @ashleyvee
i get problems like this. its just when they throw a shape in there i get confused. :/ oh boy.
so opposite sides of parallellogram are equal... \[\huge 3x=2y\] \[\huge 3 \times 20=2y\] solve for y??? @ashleyvee
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
so correct option is B
Only those 6 shapes you need to master in geometry
Theyve been throwing all of those at me. x)
I think ive mastered the square...lol
square is the simplest of them :)
master parallelogram also, it comes everywhere
i have another parallelogram question now that i got incorrect. xD
okay. ill draw it first!
In parallelogram MATH, m
@.@ ... asdfghjkl. 3x+20=5x-4? D: ?
yes thats a good start
solve x first
how do i cancel out? the x first right?
or wait.. do i add those numbers?
3x+20=5x-4 subtract 3x both sides
3x+20=5x-4 -3x -3x
3x+20=5x-4 -3 -3 ______________ 20=2x-4
add 4 both sides
20=2x-4 4 4 __________ 24=2x -- -- 2 x 2x
so it should be 56 right? and not 112?
so now we knw
i got something like 56+56=112 but i also got just 56 without adding.
Do we find a by adding 56^2?
use this :- in parallelogram, any two adjacent angles add upto 180
oops not squared. i meant 56 x 2= 112
56 + A = 180 A = ?
remember that property
:D yes!! thank you!! i keep forgetting.. :/ But i can try.
in parallelogram, Any two adjacent angles add upto 180
no try not, there is no try. remember it lol
ive tried for over 4 years.. x) it just never sticks. Im a very forgetful person. :(
u watched any eposodes of starwars
hahahah. Nope. why?
ok... nthng move on :)
move on, i must. :)
lol u knw Yoda then lol
omg. xD THANKS.
Mad skillz. :D
