Weird math question?

Test Preparation SAT Preparation
1

<p>Fwiw it's question Test 3, part 2 and question 7 of the online course. </p>

<p>It shows 2 triangles made by parallel lines and 2 intersecting lines. It shows an x and a y with their respective values. It asks to find Z even though z is no where on the diagram. </p>

<p>At first i was like 180-x-y..ez game. But then I was like AHHH YOU TRICKY college board! What if some fool wanted to put z across from the vertex of the first triangle, effectively making it z y--I chose you could not tell. </p>

<p>It turns out z was simply 180-x-y. Could anyone explain to my how we know they wanted to label Z specifically? </p>

<p>Since the lines are parallel we know which angle "is" z, but couldn't they just call that angle A or any other angle? Z could have been the angle of eyebrows for all I know</p>

<p>I'm sorry for my poor explanation, hopefully some of you have the online course and can help me out.</p>

<p>It’s really hard solving a problem you can’t see.</p>

3

<p>I know how to solve it and understand that because the lines are parallel there is one angle that SHOULD be z, but it’s not explicitly stated. I guess I’m just looking for some justification.</p>

<p>Lol woops…named it mat question.</p>

4

<p>not really weird, just a misprint, would never happen on the real sat lol</p>

5

<p>Z is probably supposed to be angle ABC or angle CED.</p>

<p>Hmm thats strange. Hopefully that was an error, I would hate to see that type of question on the actual test lol</p>
