Lets name the points to make things easier:
You can see that ADE is just a smaller version of ABC.
To find the lenght of BC, we need to compare the 2 triangles.
AB compares to AE
AC to AE
BC to DE
We already know AE, AB, and DE so it is quite easy. We set up a ratio table:
We now fill in the data we have:
We then look for BC by using cross multiplication. That means, we multiply 10 with 2, and 0,5 with BC.
Now we know that: 0,5BC = 20
We devide both 0,5BC and 20 by 0,5, so we get the whole BC:
BC = 10
EDIT: wrong ratio table, wrong answer, screw this 
Incredible.. 
Seriously, are you 14 years old...?
Either you or the Dutch school system are geniuses... |

It's easy one. Tip: https://en.wikiped...pt_theorem
PS I'm studying math.

fcancellara had the correct idea but calculated wrong obviously.
AB is 10,5m and not 10m.
And the table is correct. Only your calculation then has a mistake.

It's a very simple problem if you ask me
And I have never been good at Maths!

Here is another easy one. Try to prove it: The real part of any non-trivial zero of the Riemann zeta function is 1/2.

I figured out already
Working in a notebook is so much easier for me, I can't concentrate when working on my laptop

Haha, I did this 2 years ago during maths, but I still suck at it (at least compared to the rest of my class).
I am doing bilingual education plus gymnasium (only Latin, Greek was boring) though, which is the highest possible education for my age

I remember doing this problems in like 7th or 8th grade... I then moved on to complete college statistics and AP Calculus before I finished high school. Yes I love Math, I'm a nerd

Yeah, I did problems like that many years ago. Nowadays we learn much more pointless stuff, although I can never remember exactly what you do with pythagoras problems like that over the summer
Good thing I have Math in the 2nd semester this year, so I dont have to worry about it for a while

Just found some videos with outtakes of several songs from the 90's!
My God, the memories!
There's a fine line between "psychotherapist" and "psycho the rapist"

Don't you have a radio station that plays oldies? I listen to "Radio Nostalgic" all the time, all songs from late 60s to 90s  |

Youtube! It was one of those videos with a "medley" of 20-30 songs, I remembered every single one and it brings back very good memories!
The 90's were a good decade for me!

90s were a good decade for me, too. I especially liked the part about being born |

Spoiler My dad's sperm fertilized my mum's egg... |

What grade are you in Sweaty? With that Math I'd guess 5th. Maybe 6th.

I'm in 1st grade in High School.. The Norwegian school system is awful, you get your first grades in 8th grade! |

What do you mean? You don't have grades until your a Freshman? Or you go into High School in 8th grade?
