That was about as clear as mud!

Can not agree more😂😂

If only he could explain why he is labeling a particular term to a line, then it would have been good, but instead, he just says 'so' before doing it

[@pratyushkhandelwal7138]

Sooo Goood!

[@priyankadevgun9610]

Can you care to explain how did it become 4x/3 ?

[@xanx1234]

You said it was "asked in USA's Primary School" ............... I say BS!

[@Blubb5000]

The AI generated text meant to say: Pre-School.

Возьмём сторону квадрата за 5х. Тогда в угловом треугольнике снизу слева меньший катет будет 3х. В треугольнике выше сторона уже больший катет, а/с=4/5⇔с=а÷(4/5)=5а/4. но а=5х, 5х*5/4=25х/4=6¼х. Почти готово - ищем х через меньший катет общего треугольника: 6¼х+3х=9¼х=3⇔3¹/₁₂х=1=37/12⇔х=12/37. Найдём сперва сторону - сразу для площади числа очень большие...🙄5х=60/37=1²³/₃₇. Квадрат всего этого дела: 1+46/37+(²³/₃₇)²=1+1⁹/₃₇+529/1369=2⁹/₃₇+... в общем, много и некрасиво получается.

How we know thats the blue area is the square?

1:34 how did it become 4x/3??

[@priyankadevgun9610]

Oh now I understand long leg is 4//3 of shorter leg that is x

[@holyshit922]

At the first moment I saw it I recognized that it is excercise for similar triangles

[@irenehartlmayr8369]

So did I but one cannot expect a child in primary school to know that and figure it out exactly ! Thats nonsensical...

[@irenehartlmayr8369]

How can any school authority be insane enough to put this question to children in PRIMARY SCHOOL ? ( Assuming that this fact is even true !)...

I hate the AI generated voice. It's lazy!

[@duckdull2383]

Go ahead and make videos like this without it then

[@TheBoeingCompany-h9z]

I like the sound of the ai voice.

[@xyzgaming450]

Give the man some privacy for god's sake!

[@Blubb5000]

@@duckdull2383 Millions and millions and millions of YT videos were made before AI made people lazy. I like real voices with real handwritten scripts and not an AI voice reading a AI generated text.

[@nikolodeo]

@@Blubb5000it’s not an ai generated text, the man writes his own scripts, some people just like the privacy of it, so they use ai voices. It’s not a big deal
