Question

Help me finding out the measures?

Answer 1

First I have to figure out GF right ?

Answer 2

I think not,
BC = 40, since you have multiply FB by 2, and
GF = 30/2, since you have to apply the second criterion of similitude of triangles

Answer 3

Sorry, is DA=EF=GF?

Answer 4

LM = 90/4 since the second criterion of similitude between triangles LMB and ABC

Answer 5

Please, if I wrong tell me!

Answer 6

Since CDEF is an isosceles trapezoid, then ED is parallel to GA, KL is parallel to FG and finally measure of KL = 15

Answer 7

of course measure CD = 30+15=45
