I have 3 questions and I have a pretty good idea of an answer for some of them but im not 100% sure if they are right so ill see if I get the same answer:
1. If bh=42 what is de
2.If ab=36 what is jf
3.If ab=36 what is ke

Best ResponseYou've already chosen the best response.0looks like you've got 6 congruent segments across the bottom with a total length of 42, so what do you think DE equals?

Best ResponseYou've already chosen the best response.0I believe de = 7 but Its important that I get it right so thats why I posted this

Best ResponseYou've already chosen the best response.0Now 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?

Best ResponseYou've already chosen the best response.0Since 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

Best ResponseYou've already chosen the best response.0has a base of 14 (7*2) so to find jf, set up a proportion of 6/7=x/14 to get JF.

Best ResponseYou've already chosen the best response.0good! Now do the same thing for KE. Figure the length of the base of triangle KEH and solve the proportion

Best ResponseYou've already chosen the best response.0that's what I got as well: x/21=6/7. x=18 I think you've got it!
