The snag is that these four shapes seem to form a triangle together, but it isn't a real triangle! Compute the areas of the shapes:

Yellow: 7
Green: 8
Red: 12
Blue: 5
Total: 32

Together they seem to form a triangle with an area of (5 * 13) / 2 = 32.5

In the first case, the shapes together form an area of 32, which is 0.5 less than the area of triangle they seem to form. In the second case, they form an area of 33, which is 0.5 more. So the difference in area is 1, and that's the "hole" in the second area

The tricky part is the hypotenuse of the "virtual triangle". The steepness of the hypotenuse of the red triangle is 3 / 8 (= 15/40), that of the blue one is 2 / 5 (= 16/40). So the one of the blue triangle is a very little bit steeper. You almost don't see it, especially if you draw them on a grid...or can you see it now?



MUHUHUHUHUAHAHAHAHAHHAHAHAHAHAHAHAHA

you can see the arc better in this.

Fuck tetris

Way to copy and paste it from the site n00b.

Because most people have seen that posted a million times before and remember the answer. They wouldn't have been so quick off the mark when it was originally posted.

my point exactly
people don't remember how to do math, they just remember answers to colorful problems

If someone hasn't seen this , before TA, I find that hard to believe. I've seen that puzzle in most elementary school books.

Use the number 3 in three different combinations - Seven, Eight and Nine times respectively - so that the result is 100 every time. You may group the numbers in any way you like.

Example:
Using it seven times: 33 * 3 + 33 / 33 = 100

Do it using the number 3 Eight times and Nine times respectively.

33+33+33+(3/3)=100

I dunno nine

pretty similar to 8.

33 * 3 + (333/333) = 100

(333 / 333) + 33 * 3

My first inclination when i saw this thread tonight was x = 19 as it looked like an equilateral triangle.

Pythagorean theory can be applied to both isosceles and scaline triangles, of which this one wasn't.

ps. i think it woulda been arctan...it's been a while lol

That was an excellent display of nerdiness being applied. You should repost it

Originally posted by eRRaTiK hmm... that was my original guess too. so is it an equilateral triangle? or is it isosceles? There's no angles represented so it's hard to tell. stupid snail.

the fact that each side has a line through it means they are all the same. stupid erratik

edit: oh, and people that see a right-angle in that picture should be shot.

pffftt. it's been like 15 yrs since i learnt that shit lol

alright alright...


sin (33)
-------- x arctan (33) + 33 x 3 = 100
cos (33)

yeah, its amazing that in that 15ish years none of us have had to remember that until now. man, maths was so useful!!

I remember using trigonometry when I was designing my simple greenhouse.

I have some pretty fucking bosh qualifications in maths and further maths.


Can hardly remember any of it now.

I have 9 University Calc Credits (obtained in high school through an AP program) and I haven't got a clue with regard to any of it at this point.

Huzzah for easy to get AP credits and never having taken an actual University Math Course.

Hope your pretty then, otherwise you might have a fine career lined up as a stripper.
