first😊

Ok, only works in equilateral triangles.... Still interesting

The most interesting aspect of this question to me is - Is it really ok to count the same pieces multiple times?

there are 41 triangles.

Question answer is 78.6 not 5 cause of rounding off

Every object after the first 4 triangles has an interior angle greater than 180 degrees so not triangles.

10 x 4 layers is 40

I counted 96.

Please speak in hindi

40 (4+3+2+1)4

53

I got 40, and the reasoning that that was all of them was sound and I knew it was sound. But I still spent a bit looking for the sneaky extra one(s) before I played the video.

I see 40 in the thumbnail

I saw freaking 28

I see 20

kto od buddy? :D

Each triangle has at least one corner in the bottom left or right. There are (4+3+2+1)*4=40 triangles with a corner in the bottom left. 4+3+2+1 describes the widths, and *4 describes the length from the bottom left. The right hand side is the same except we don't want to double count truangles with corners in the bottom left, so we have (3+2+1)*4=24 for a grand total of 64.

I count from largest to smallest, 40.

Error lol

Worst explanation i ever seen in my life

Thank you!! But can you explain how you got -1 for p in question 13??

I did will a slightly different method. Find the area of the purple sectors with a green triangle. I then find the area of one the green triangles. I subtracted the area of the green triangle from the sector. That leaves with the area of the purple segment outside. I them added the result with the area of the first sector. Multiplying that by 4 would then give me the area of the four green triangles and the eight purple segments. Next step, I looked for the area of the circle and then subtracted all the other areas from it. Same result was obtained.

We can see there the big Pentagon And one small Pentagon. If I take only 3 pointy * from the big Pentagon, there Is C(5;3) triangels. If I take 2 ** from big Pentagon, 1 ° from small Pentagon, there Is 15+5 triangels (15 from , 5 for *-----*). For one point * from the big Pentagon , two ° for small Pentagon I have got only 5 triangels.

I got 47. Must have double counted some.

This is brilliant - thanks very much for sharing. Is there any possibility of adding a link to the question file in the chat? 🤔

You have officially saved my life. ❤❤❤❤❤

40

U missed a few for example the middle line divides the biggest triangle into 2 smaller right trangkes 😊

I see as many triangles as I see.

All of them

I get 40

what about half the sum of four consecutive numbers

I got at least 40. Let's see...

56

Thanks for sharing!

40 but if you rotate the triangle then 40x 3= 120 combinations

Bro its fuckin 4 you cant just ignore the lines.

Thank you dear mr and mrs

there are 5 diagonals and you need to choose 2, there are 4 horizontals and you need to choose 1: 5C2*4=10*4=40

4 times 4!. HAHA
