1. If bh=42 what is de
2.If ab=36 what is jf

looks like you've got 6 congruent segments across the bottom with a total length of 42, so what do you think DE equals?

I believe de = 7 but Its important that I get it right so thats why I posted this

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?

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.

so JF would be?

good! Now do the same thing for KE. Figure the length of the base of triangle KEH and solve the proportion

Yea I got 18 but im not really sure if its right

that's what I got as well: x/21=6/7. x=18 I think you've got it!
