The solution for the ragebait math problem

[Aypo129]

You didn't really gave an explanation well
Why was the base extended to 30cms
Did you copy this question from somewhere?

You math major math white guy? or just math interested asian

80- 50 = 30 do I have to explain basics??

 

[Aypo129]

For example if you used cos thetha then why didn't you write the angle
This explanation will confuse people

I didn't use cos theta at all

I only used only basic similar triangle, pythagoras and changing shapes you clearly don't understand my solution

@Aypo129 @imontheloose

These indians don't understand math at all JFL

they don't even know 80-50 = 30 and how it becomes a straight line

 

[widdi]

a "line is a collapsed triangle" is only in the degenerate sense, that is, when one side of the triangle equals the sum of the other two sides, so the figure flattens into a straight segment and has 0 area. but that is not the usual, non degenerate situation where each side is strictly less than the sum of the other two, and the shape encloses a positive area. "a line is a collapsed triangle" does not mean every triangle (or pentagon) can be viewed as "the same thing" with area 0. Degenerate and non degenerate shapes obey different side/angle conditions, leading to fundamentally different geometrical outcomes (zero area vs. positive area) which was my point

well my point was that both of them can be used interchangeably because every line in a triangle is also a collapsed triangle so you can put 2 side by side and have it work out to a 180 degree angle

 

[ngannou]

well my point was that both of them can be used interchangeably because every line in a triangle is also a collapsed triangle so you can put 3 side by side and have it work out

He just doesn't admit the fact that he is wrong so he will keep yapping with nonsense

 

[Aypo129]

You mean the similar triangle law
Corresponding sides do not become equal in similar triangle they are proportional but not the same size

You should clarify that step

 

[Aypo129]

Corresponding sides do not become equal in similar triangle they are proportional but not the same size

You should clarify that step

You need to prove congruency if you want to say their equal

Its like common sense

 

[imontheloose]

yeah a line can be viewed as a degenerate triangle but that doesnt make them interchangeable. not only the zero vs positive area, but the side length constraints and the angles prevent it no? its a limiting boundary saying AB+BC=AC. doesnt it break core theorems when heading forward too? you cant use them interchangeably in proofs or constructions that rely on non degenerate properties AFAIK

 

[ngannou]

Anyways it become a straight line

if three angle conincide at one point and 180

 

[Aypo129]

Its like common sense

Which book did you copy this problem from can I see it

I bringed the official answer go translate it

 

[widdi]

ye he has to prove that angle tsr and tpq are the same (from the textbook) if he wants to do a direct proportion.

 

[ngannou]

Nice

∠ABC+∠ADC+∠DAE = 180degree,
∠BAC + ∠ACD+ ∠AED = 180degree,



So that’s why it will be same

 

[Aypo129]

ye he has to prove that angle tsr and tpq are the same (from the textbook) if he wants to do a direct proportion.

Yeah it's mistake to not show
Theres a logic behind the same angle
If these two angle match the cos thetha of these angles would make PQ and TQ same t

That's why it's important to show it's the same

 

[imontheloose]

lol i just realised i assumed something totally wrong, while what i said was right, it obviously was applicable here i just thought it wasnt. nice going @widdi, although obvious, you somehow managed to make me spot that i just read an angle constraint incorrectly i missed my thermodynamics lecture just to ponder on this lmao

Since

∠ABC+∠ADC+∠DAE = 180degree,
∠BAC + ∠ACD+ ∠AED = 180degree,

180 - 2theta = angle pqt

And angle qrs is 180- theta
So srt becomes theta I mean it is so simple so I don’t think I have to add this. I don’t have to explain it out

Finally you admitted

 

[imontheloose]

your explanation wasnt making sense and i didnt see how i was wrong, finally i spot i read an angle constraint wrong, such a silly mistake too lol

 

[Aypo129]

Even simple steps should be mentioned it's important part

So now you understand everything no more questions?

yup, my first explanation to you was funny enough exactly what you did but i assumed they constructed it so it would be a multiple of a easy pentagon's area instead of all these intricate shapes. nice to see it actually done however, i couldnt imagine all the cross products and trig sim. eqs. trying to do this from scratch lmao

What does it mean multiple of easy pentagon area I don’t understand show me the real diagram if you have time

 

[imontheloose]

for example, a square can be represented by two triangles

So you saying you can split that pentagon to a smaller pieces of pentagon?
Or saying you can use that pentagon consist of bigger pentagon

 

[imontheloose]

it depends on the question, in different questions you merge those shapes into other shapes to simplify the calculations

So what were you trying to do in this question merge it or split it

 

[imontheloose]

So what were you trying to do in this question merge it or split it

i didnt attempt it, i was just telling you that youd need to split it into parts and find a better shape to work with which is what you did.

at the end i also stated how youd probably need to prove the area stays the same with one degree of freedom so just differentiate the area and prove it equals 0

So many stemcell indians got mad for this question because they couldn't solve it
so I am posting the solution

Anybody smart with math???? come here.

There are lots of currycells here who study days to day on math. I see bunch of Muh Jee Advanced in math youtubes everywhere muh we have the smartest IT workers. I just found a mind blowing geometry question that looks complicated but could be also solved in only one simple calculation. Let...

For convenience lets say
∠BCA = ∠c
∠CAD = ∠a
∠ADE = ∠b


View attachment 3517795

We know that angle sum of a sides of 5sides is 540 degree

and angle
∠ABC+∠ADC+∠DAE = 180degree,
∠BAC + ∠ACD+ ∠AED = 180degree,

we can get the remaining angle ∠c + ∠a + ∠b


The sum of angle of whole - (∠ABC+∠ADC+∠DAE) - (∠BAC + ∠ACD+ ∠AED) =

which is 180 degree.



Now here is the creative trick

everybody knows that the angle of a straight line is 180 degrees.

View attachment 3517799



We can flip the triangle ABC and Triangle ADE


to make the angle c,a,b coincide in one point and make a straight line.

Thus we had 5sides but not it turns into 4sides making it simpler but still

maintaining it's area.


View attachment 3517815

INow we re label the points of new 4-sided shape as a,b,c,e

and the angles.

We can extend the line ae and bc until it conincides and if we say that coinciding point as d

and we can know that the triangle abc and triangle ecd are both

isoceles triangle and similar to each other.

So if we use the ratio we know the length of ad = 96cm


View attachment 3517821




Now the last to step is to get the area by subtracting the area of
triangle abd and the area of triangle ecd.

You can get the height of each isoceles triangle using pythagoras.

The required knowledge is basically elementry middle school level
