Answer 1

@SolomonZelman

Answer 2

I know z is 7.

Answer 3

if you think about it, the smaller triangle is similar to the larger one, and based on some theorem, the angles will be exactly the same. it's been a year since i took geometry, but i remember that. based on that info though, what do you think y is?

Answer 4

actually you dont even need the two triangles being similiar, the midsegment is automatically parallel to the base

Answer 5

well there you go! i knew there was something easier, i just didn't remember :p

Answer 6

There is no way you can find out what the answer is if they don't tell you z and 14 are parallel. There is not enough information to say what y is equal to.

Answer 7

the answer is 63, by midsegment theorem

Answer 8

@seratul
midsegment theorem says they has to be parallel

Answer 9

It is 62!

Answer 10

@caozeyuan alright
