OpenStudy (gabebae):

that's semester

OpenStudy (gabebae):

pretty sure it's EOC practice

OpenStudy (anonymous):

its not for the collab. u just get help on live lessons

OpenStudy (gabebae):

they're pretty must going to do the collab in the live session

OpenStudy (anonymous):

OpenStudy (gabebae):

it's a semester two review

OpenStudy (anonymous):

its the same thing?

OpenStudy (gabebae):

I don't think so.. I think it's EOC review

OpenStudy (anonymous):

EOC lessons are specified.. The semester exam review is going to review moduless 6,7,8, and 9

OpenStudy (gabebae):

I just need help with Module 9 I took the module 9 exam part one and got a 80 I'm too scared to take part two , which is response questions

OpenStudy (anonymous):

oh just post the questions on here

OpenStudy (gabebae):

I don't think people will help me I ask a lot of questions and no one helps geometry is a nightmare

OpenStudy (anonymous):

ill help

OpenStudy (gabebae):

You didn't take module 9 yet

OpenStudy (anonymous):

i just read itt hah but in algebra 2 i did those stuff cause i finished early and they started teaching geometry

OpenStudy (gabebae):

So you know how to find missing angles?

OpenStudy (anonymous):

i cann

OpenStudy (gabebae):

OpenStudy (gabebae):

I don't know most of these questions I just read them and i'm freaking out

OpenStudy (anonymous):

ill tag some more people too @nincompoop @ParthKohli @baru @satellite73

@Michele_Laino @paki

OpenStudy (anonymous):

why is no one helpingg

OpenStudy (jadedry):

Regarding the circle question mentioned previously; couldn't you prove they are similar by drawing triangles within the circles and showing that although the sides of the triangle in circle b are longer, their angles are equal ?

OpenStudy (gabebae):

I don't know how to do that

OpenStudy (jadedry):

? One sec, let me illustrate.

OpenStudy (jadedry):

|dw:1452177477475:dw|

OpenStudy (jadedry):

use the graph as a guide for the length of each triangle.

OpenStudy (jadedry):

Keep in mind that I'm not in FLVS so maybe I'm not thinking the way I "should".

OpenStudy (gabebae):

I still won't be able to find the angle

OpenStudy (jadedry):

|dw:1452177591436:dw|

OpenStudy (jadedry):

you could use a right angled triangle

OpenStudy (jadedry):

Remember your trig rules?

OpenStudy (gabebae):

no

OpenStudy (jadedry):

Sin tan and cos? You can find the angles since you have the length of all the sides

OpenStudy (gabebae):

ah yes I know those..

OpenStudy (gabebae):

I

OpenStudy (gabebae):

*I don't think these were mentioned in this module though

OpenStudy (jadedry):

Hmm. Did you perhaps do it in a previous section?

OpenStudy (jadedry):

I fail to see why this cannot be a valid route, was there anything that the course highlighted that I should know about?

OpenStudy (jadedry):

Technically all circles are similar, so..

OpenStudy (gabebae):

hold on let me open up the notes

OpenStudy (jadedry):

Alright.

OpenStudy (gabebae):

We can find the arc length and and area of a sector

OpenStudy (gabebae):

That's mentioned in the lesson

OpenStudy (jadedry):

Ooo, okay. One sec let me gather my thoughts.

OpenStudy (gabebae):

Arc length formula = n/360 * 2*pi*r

OpenStudy (jadedry):

Arc length of whole circle = 2 * pi * r Area= r^2 * pi
