<p>the angle thing is two. draw it out and picture the lines moving. you can only have 2 obtuse angles</p>

<p>yeah i think it was 2, i edited it on the last consolidated answers post on pg4</p>

<p>@bhchamp you are correct</p>

<p>how bout the one with the poles ?? was that 7? and are u sure its more than 3, isnt it none?? and for the a+b/2 i got 2 and 3, could someone check that ? does anyone know which math section was the experimental one</p>

<p>Did anyone else feel that the “her watch is ahead 7 minutes” was too vague? The word ahead is intentionally confusing. maybe i’m just angry that I got it wrong, but it was kinda obnoxious</p>

<p>Did that (r,s) question really ask for the x value of the x intercept? I coulda sworn it asked for y value… no?</p>

<p>I got (-1)^11
And three angles with 91 degrees each works.</p>

<p>it asked for the x value, I am 100% sure</p>

<p>@superreader yes but if you had 3 angles with 91 degrees there is a vertical angel of one of them that is also 91 degrees. thus you would have had 4 angles with 91 degrees which is incorrect.</p>

<p>@unrelateduser</p>

<p>I hate stuff like that too because I get confused easily with words like that & time</p>

<p>but If you think about it a clock that’s ahead is 7 minutes past the current time</p>

<p>i asked for s, i first put -2 but then changed it to 0</p>

<p>It was the x value of the y intercept, so it was 0</p>

<p>what was the problem for the grid in that u guys got n = 122 cuz i forgot ?</p>

<p>@loku, it was the sum of the digits for 1001 to 1020</p>

<p>the pole in the street question???</p>

<p>Wait why are you guys getting 122 for the sum of the digits 1001 + 1002 … 1020?</p>

<p>Wouldn’t you have to add 1+2+3+4…20 and then add 20 for the 1s at the beginning?</p>

<p>me and my friend got 230 for that bc u have to do 20 + 1+2+3+4+5+6…</p>

<p>@BeccaN
1001= 2
1002= 3

1009=10
1010=2
1011=3 </p>

<p>it resets at 1010</p>

<p>Ohhhh makes sense oops.</p>

<p>guys for the angle thing shouldn’t it be 4?
look at the picture

<p>if the angles are small enough (say 35; 36; 35; 36 because of vertical angles), when we add up 4 angles it’s 142 < 180 and also >90</p>

<p>craapppp i looked at that wrong</p>
