x=50

>>716688326
smart enough not to solve your homework

Or maybe x=30, i'm confused

>>716688604
Yeah x=30

60 degrees

Is bottom right a 50 or 60?

>>716688741
wait no it isnt, i thought the bottom one said 60

>>716688326
>>>/x/

>>716688916
It's 30. I don't care to explain because I don't know exactly what the rule is called, but its used for proofs in geometry. Somethinf about reflex angles I believe.

Answer is 30

The answer is 30. needs a little construction but do able, only works though if the integral of the upper triangle is congruent. Wouldn't make sense if it wasn't though

X=60 (if bottom right is 50)
The rules i used to solve:
Opposite angles in a cyclic quadrilateral add to 180
(Add the two bottom left hand angles *20 & *60 = *80)
Then using that angle of 100 degrees we can work out that *X + *the angle next to it = *100. From there using rules such as *triangle sum = *180. We can solve that *X = 60 and the angle next to it is *40!

YOU NIGGERS! YOU DO THAT STUPID "Z" THING TO GET IT! X = 30

It's like I'm watching kids! Fuck bois!

4 angles produced by 2 crossimg lines, all with an different value... every 4th grader knows youre wrong.

>>716689675
How is the opposite angle of 70° 108°. Arent they supposed to be the same?

>>716689675
108? 42? are you fucking stupid?
Middle is a cross which angles add up to 360
across 70 should be 70
and that 120 should be 110 because 70+110=180=a straight line
add another straight line and you get 360 jesus christ youre a fucking retard

>>716688540
WORKS

>>716691104
Yes they are, he's just retarded

upper right corner

>>716691226
The answer is right, you know? The first step had to be missed in order for the next one to work, it balances itself out once you have the first corner

>>716691976
Dont know why it looks like shit... ill try again

>>716688326
x is 80 because that line used for angles mean that the angles that have 1 arc on them are congruent, so 20+60 is 80 and 50+30=80 and x has that same line on it so its 80 regardless of your shittily scaled image

>>716692562
That was a good one. I spent ten minutes trying to solve the damn thing before giving up.

x can be any angle given that 0 < x<110 you cunts

>>716695673
No it cant retard
The angles make for set crossing points, so the angle of x is set

>>716695788
Nope, with the given information as best you can get 4 equations that are not linearly independent, thus meaning that all we know is x + y + 70 = 180, meaning that x can be any angle 0 < x < 110

Yes, more difficult than expected. And not a single convincing solution by not.

It cannot be really tall. The right triange has 60/80/40 degree. which means it is about as hight as wide.

Fools, do not argue with Lecart, the God of simple geometrical problems. The answer is 20

>>716696357
20 30 is written on the pic

>>716696284
what's triforce?

>>716696696
So how does this give 60/50 then?

>>716688326
x=40.

the triangle is an isosceles and one of the angles is 70 (180 = 60 +50+n, therefore n=70)

>180 = 70+70+x
>x=40

Yw retards.

>>716688326
You can't calculate x as a single value - it can take a range of possible values. And you're going to go "yes you can", in an attempt to keep the chimps that inhabit this board banging at their keyboards rather than flinging their feces around the place. But nevertheless, you can't calculate x as a single value. Perhaps you'd like to get them trying to square the circle next?

>>716696484
youre stupid

>>716696879
>isosceles
The 70/60/50 triangle is obviously not a isosceles.

>>716692146

Why is no one acknowledging this?

>>716696930
So what is missing to get a unique answer?

>>716696659

x+y = 110 , if you don't understand why if you don't understand why kill yourself with fire.
We construct FG to be parallel with BC.
In triangle FAG you have the equation : x + (180-y) + 70 = 180. Thus x + 70 = y. Thus going back to the first equation x is 20 and y is 90.

>>716688326
X=top, right of center.

/thread
All hail Lecart , the God of simple geometrical problems

>>716698063
shouldn't at F (180-y) read y and vice versa?

>>716698063
First you say an angle is y, then the same angle is 180-y
Proof: other 2 corners in the triangle (FAG) are the same as the other 2 corners in the top triangle in the original pic

>>716698063
So basically the problem is " find FAG". We have a simple solution:

You guys are bunch of retards. Can't even do simple task

>>716698063
except angle BFG is not 180-y, it's simply y you fucking goon

>>716700619
But if y is 90 then y is the same with 180-y

>Says it's a right triangle.

Which is it?

>>716692146
You both are fucking idiots, congratulations.

>>716688326
Assume a coordinate system and put the lower left point at (0,0) and the lower right point at (1,0).
Then the top corners will be at (0.9848077530122079, 0.1736481776669304)
and (1.3268278963378763, 0.7660444431189779).
This again results in x=30 degrees.

To calculate yourself use (1/(cot(a)+cot(b)), 1/(1+tan(a)/tan(b))).

Yes, this is probably the most complicated solution, but it proves that there is indeed a single correct answer and it is 30.

Easier solutions welcome. :)

>>716704298
both? you cant even quote right kys

>>716704327
That's also assuming the drawing is 100% to scale, and since the answer is 80, because the congruent angle arcs, it isn't.

>>716704744
The length of the lines do not matter. the angles stay the same. Just try the calculation with a different base size.

80 degrees makes no sense at all. that would mean that the left corner would be higher than the right one, which cannot be. - try to draw that. ;)

>>716705911
Rescaling something doesn't just make the entire thing bigger or smaller, it can make any specific part bigger or smaller, so you are incorrect about it not changing how the angles appear. In this case scaling the image correctly would fuck it up a lot. It's possible to scale it correctly, it just changes the whole image and is way too much work.

30 degrees.

Hint: draw additional line segments to create some new isosceles triangles.

>>716708285
Your triangle to right totals 190 degrees, gj son

>>716689675
Boi, you forgot that all flat lines are 180 degrees so the interior angle of triangle x cannot be anything other than 70 degrees. Nice try and I do appreiate the effort you have put into this.

>>716692746
Finally, someone who knows what they are doing.

ok,
i am good in math and i don`t get any single solution, i checkt it 3 times and there were no mistakes found.
if you try to find a proper answer you will see that there is no single correct answer to the problem because there are to many variables

>>716709729
>good in math
>cant solve 2-variable system of equations

hows 5th grade?

>>716710226
you have not solved or at least try to solve it ether, because you need a third variable und if you try the system of 3 equations somthing like y=y or z=z appears, which means that there is no single answer..... so i am able to solve them but in this case it is not possible

if i made a mistake please inform me, even tho i checked it 3 times
