@zepdrix can you please quickly help me with this? i need to go to bed soon. :)

Answer 2

So you have a bunch of similarities being created.
Here are two of the triangles.
I rotated the bottom one.

Answer 3

Do you know how to set up a proportionality to solve for b?

Answer 4

nope

Answer 5

So that smaller triangle is just a scale factor of the larger one.
(It has been shrunk down my some factor.)

If we look at the ratio at which the hypotenuses changed,this should be equivalent to the ratio of any other set of sides (since they all are scaled by the same amount).
