anyone notice a mistake on the sat nov 09 test?

the one with 3 intersecting lines and a triangle....

angle b is supposed to be 40 but there was no answer choice for that..


....stupid collegeboard

belleisbelle

question also:
if i omitted 6 questions in cr, what's the highest score i can get?
i know i shouldve guessed up to 4....

totally unfair, thought everything was extremely easy until that children and television essay (my section 9), which was structured hell
why the frick do they have to choose essay writers who alwaaaayss divulge from one thesis to another???
like that stupid woman artist who went from talking about child-prodigy myths to women and society.

^ When I got up to that, I omitted like 6 questions in the end due to the out-of-time. How dissapointing.
And I only wrote 2/4 of the essay. =/

Belleisbelle, there was an answer to that question. You just had to plug in the answers for b to see if it makes sense. Did you ever consider method # 2?

belleisbelle

yes

60 (180-120) + 40 (b) + 80 (c=2b) = 180

wait

they didn't ask for c did they???????

SAT Law #1) The test doesn't make mistakes. If you think there's a problem with a question, there's a problem with you.

keekdapolak

that one came out to like 60 or something. i got the answer for it

belleisbelle

explanation?

i got 60 the first time, plugged in the answers, came out way too big

the given info is

a 120 degree supplementary angle
c = 2b

right???

if you plug in 60 doesnt it come out 240?

i am confused, explanations? corrections?

choklitrain the test makes very occasional mistakes. and also collegeboard itself is a problem

ChoklitRain

^ and people make much more frequent mistakes. never assume a question is flawed.

belleisbelle

can you least post an explanation? jeebus

You can find that one of the angles is 60 (the leftmost one on the triangle) using I forget what, but I know that one angle was given as 120 and that angle measurement (the 60 one) was found by (360-240)/2. Then you know that 180-c is equal to one of the angles and b is given as the other angle. Since c=2b, 180-2b is the angle of one of the angles in the triangle. So, you get (180-2b)+b+60=180, which simplifies to 240-b=180. Isolate b and you get b=60. The answer was there, you just didn't know how to do the question you silly goose. Don't blame collegeboard! Although I almost second guessed them on that one with the line passing through (2,4) and not through (0,0), but then I remembered that line = linear :P

belleisbelle

wait a minute
was 2b outside of the triangle or inside??

motion12345

C was outside the triangle, and so I guess 2b was outside of it as well.
