I think it was my fault so dont worry hahah

looks like you've got 6 congruent segments across the bottom with a total length of 42, so what do you think DE equals?
anonymous
  • anonymous
I believe de = 7 but Its important that I get it right so thats why I posted this

yep

Now for the others. You have a triangle with one side of 36 (that's AB) and another side of 42 (BH). All the other triangles as you move across from left to right are similar to the biggest triangle (ABH.) Are you with me?

Yea

Since all the triangles are similar, the proportions of their sides are the same. So 36/42, which reduces to 6/7, is a common proportion in all of the triangles. For example, triangle JFH

has a base of 14 (7*2) so to find jf, set up a proportion of 6/7=x/14 to get JF.
anonymous
  • anonymous
so JF would be?
anonymous
  • anonymous
12

  • anonymous
good! Now do the same thing for KE. Figure the length of the base of triangle KEH and solve the proportion
anonymous
  • anonymous
you doing OK?
anonymous
  • anonymous
Yea I got 18 but im not really sure if its right
anonymous
  • anonymous
that's what I got as well: x/21=6/7. x=18 I think you've got it!

Alright well thank you so much!
