70 d

No it doesn't make sense faggot

It's been 14 years since I took geometry in high school. I probably could have solved this back then.

x = y

x = 0

x is all solutions

can't be done. this was created by a cunt

yes it can

25

60

30°

I'm shit at math but it should be around 30

wolframalpha.com/input/?i=60 + 20 + 50 + 180 - x - 70 + x + 40 + 30 + 50 = 90*4

Well, we're waiting....

...

x cant be anything

30 degrees

look how smart i am i can use google

Where did you get that 75?

...

Wait He did (180 - 30) / 2 = 75, you cant just assume the 2 angles are equal?

10 degrees

30

youre wrong dummy
lrn2geometry

As far as i can get without assuming angles

Idk if it counts as cheating but using a ruler + compass I could solve it.

it doesnt count as cheating, it counts as wrong
youre foolishly assuming the angles in the problem are correctly drawn

as far as i got as well

yeah, it's cheating, in fact it doesn't have one solution for x, cause you can draw the bottom right corner following the diagonal line varying the x angle and conserving the originals angles.

extend it into a bigger triangle niggers

80, 60 plus 20 is 80. those added up are congruent to x, as you can see with the congruent angle marker. This problem is shit though and obviously not drawn to scale.

im not talking about scale the whole thing, imagine you drag the bottom right corner, you still got the angles from the image but x is change, therefore x you can make x as big as you want

Well, not if you have these handy dandy tools. I'm a Civil Engineer student.

> needing those to do a simple geometry problem

How's feenix yuniversitee?

30

Well, be my guest, noble gentleman, prove it with algebra and trigonometry then.

0

As far as I got, too.

well, its a shit problem. technically its 80 because its saying x is congruent to the other 2 angles (30 + 50) or (60 + 20) which are both 80. its a bad problem.

might be wrong tho

that's because there are infinite solutions as long as that's true

you are

Wrong. You cant assume that the left big triangle is isosceles.

Bullshit, that would change the 20 degree angle.

either not good at math or don't know what infinite means

Got 55°.

nah

Fucking dumbasses

there are is an infinite set of numbers between 0 and 110. Angles don't have to be whole numbers you dumb fuck

No, that user made a correct statement. There are an infinite number of solutions to 0 < x < 110.
> not all numbers are integers

Ugh, this is going to be some big huge "law of cosines" problem, huh.

there is literally no way to do a cosine with the information given

here you go now fuck off

It has to be 30 d

>180-110=40
Impressive level of retardation on display there. Wrong answer too.

You're assuming an isosceles triangle

This is the correct solution. Thank you for thinking outside the box.

piss off it's 5am for me

THIS IS THE ONLY CORRECT MATHMATICAL SOLUTION.

No, he's saying the OP wants 70 d's.

You are wrong

Why are you assuming that it is an isosceles triangle? Protip: you can't

so you're gonna tell me im wrong without saying why? okay.

it's 30. Any other answer and you are retarded. I am a red seal machinist and do this all day long when I create drawings. I machine Hydraulic cylinders and engineer CnC Aircraft parts using mills, lathes, verticles, and boring mills.

go machine yourself a dildo.

...

Mathematician here. The answer is X=30°
Thank me later.

draw the equilateral triangle and find 30

Wow you guys are dumb. It's pretty obvious that it's 60, and if you didn't figure this out within like 5 min just kys.
Let me explain to you snowflakes why:
The whole thing is a rectangle, the sum of its angles therefore has to be 360. We got 80 in each top corner (50+30 and 60+20), now that leaves us with 160, 200 remaining. take the 200 and split it in 2, because if the other two are symmetric then the remaining ones have to be as well in order to logically connect as a rectangle. Now just take the angles we have already (instead of going for the ones in the centre as some of you autistic horses tried) meaning the left part of the top left corner (20) + the WHOLE bottom right corner (which is 100) gives you 120, and boom only 60 (=x) left to 180 (total sum in a triangle).

Get on my level faggots

One true solution right here

How do you find the 80º without relying on the representation proper?

Already been posted, faggot:

>not even a single fucking angle is 90 degrees
>"rectangle"
kys, faggot

Fuck user you beat me I was turning my pc to graph it on autocad too. This is the real answer.

This is correct. Congrats!

While you can mirror the one triangle to the lower-right, you have not shown it forms a straight line with the other line, so you can't assume the 3 angles sum to 180.

Can it be done without trigonometry?

Do you look like this? If so then yes.

No

He didn't assume, he drew so it would be 180.

Aren't the values necessarily wrong, given that:

The missing angle in the upper triangle is:

180º-110º=70º

Hence the central angles are 70º, 110º, 70º, 110º, clockwise from that missing angle.

Consequently, the now missing angle in the left traingle is:

180º-30º-110º = 40º

And the missing angle in the right triangle is:

180º-20º-110º=50º

Because we know that the central angle that is a missing angle in the lower triangle is 70º. we also know that X and the other missing angle add to:

180º-70º=110º

Thus we know all internal angles for the rectangle:

30º+50º=80º (upper left corner)
60º+20º=80º (upper right corner)
110º+50º+40º=190º (bottom left + bottom right corner)

That only adds up to 350º, however, so the values for the angles must be wrong.

What exactly did I miss here?

triangle*

Epic fail in the last sum, also. 110+50+40 = 190? Really me? That is 200. Time to go to sleep.

Tomato

X+Y(lower right) = 110, that much is known.
Except the shape has no room to change at all.
Every other angle is defined.
Giving it an arbitrary size of 10 at the left side(the shape, presumably, is scalable; it could have any real number as a measure) we delve further using trigonometry:
Applying the laws of sines and cosines we calculate the upper line, lower left diagonal, right line and finally lower right diagonal, all to scale, then the lower line.Finally, x equals (approximately) 29.977 degrees.
It's probably 30º then.
Prove me wrong(really, try other initial line sizes, higher precision, other methods).

180 = x + y + 70
110 = x + y
110 - y = x

180 = 30 + (40 + x) + y
150 - y = (40 + x)
110 - y = x

180 = x + (y + 50) + 20
160 - x = (y + 50)
110 - x = y

Anyone who gives an actual answer that's not
or
Goofed real bad.

30 degrees. I'm too far from school for cute tricks, so I used:

1) Basic triangle properties to get all the angles except x and 110-x
2) Law of sines to get all the sides except the bottom line
3) Law of cosines to get the bottom side
4) Law of sines to get x and 110-x

X=30 degrees

except the problem did not give you a side you faggot

Same, maths proven, at least we don't need software and rulers huh?

The length of the first side is irrelevant if all you need to deliver is the angles. Set the top line equal to 1, figure everything based on that. The angles remain the same regardless of the actual value.

Learn math.

Retards

Nice.

I didn't see your post, I used the same methods (more or less) and got exactly 30 degrees.

Nevermind, I can't assume an angle of 90º in E is continuous with the bottom line of the rectangle. 30º is likely correct instead.

You had more errors than just that. Y is 80 degrees by the way you set up E, and tells you nothing about x or Z.

was this supposed to be hard???

If you (a) want an exact answer and (b) can't assume that the drawing is accurately drawn wrt to angles, then it is tedious but not hard. Otherwise you can do as you did and give a program the question and accept the approximate answer, which is easy.

Did I invert Y and Z when I gave the values? Because otherwise, while the assumption was strictly an assumption, and hence not a solution at all, WITHIN the assumption the value of Y was already given as 80º, and tells me about Z, and consequently X, because within the assumption Z+Y+50º=180º.

It is exactly because Z+Y+50º does not necessarily translate to 180º there that it is wrong and merely an assumption, but that does mean it is not a further error, but merely a logical extension of that one.

Draw it and post, showing Y and Z explicitly, and we can talk coherently.
