Question

Find z: (image in comments)
a. 2
b. 13
c. 8
d. -2
e. none of these

Answer 1

I think we can do something like this.
Because AB and DE are parallel, that means that angle BCA and ECD are equal

Answer 2

and so the sides opposite those angles are equal too

Answer 3

alright i see what you mean

Answer 4

so if AB and DE are equal, what is the next step?

Answer 5

to figure out the angles?

Answer 6

no, we're looking for z.
the angle measurements are irrelevant

Answer 7

so we need to make the equations equivalent since the sides are too?

Answer 8

yus

Answer 9

this is an odd question I'm not sure I'm doing it right

Answer 10

hm okay lol let me see

Answer 11

well the sqrt75/sqrt3 equals 5. should that matter at all?

Answer 12

not really because you can figure that out from the angle relationships

Answer 13

yeah i have no clue. these angle/triangle questions throw me off every time.

Answer 14

I forget what this relationship is called but yeah
