I need to find m<1 through m<6

very simple problem :)...so elts look at angle 2 first...wat do u notice?

u should notice that one angle is defined as 40 degrees, and the second is a right angle (therefore 90 degrees), and we know that in a triangle, all angles sum up to be 180 degrees right?...therefore for angle two, just subtract 40, and 90 from 180, leaving u with 50

- anonymous

so 2= 50 degrees.

- anonymous

I look at your example. Please give me a sec

- anonymous

sure!

- anonymous

Ok, I understand that one.

- anonymous

so its basically the samething with every triangle that has 2 angles already defined right?

- anonymous

so now try and find angle 6

- anonymous

Would 6 be m<6=50 degrees

- anonymous

YES!

- anonymous

there you go u understand it!

- anonymous

Would m<1 be 35 degrees

- anonymous

now...lets look at 4....4 is located on a straight line, meaning that that angle plus the one given beside it (60) is equal to 180 right? so simply do 180-60

- anonymous

yes m1 is 35!

- anonymous

umm. so m<4=60 degrees?

- anonymous

no m4 is equal to 180-60 degrees. do u understand why its 180-60?

- anonymous

(120 degrees)

- anonymous

Ok, Sorry I miss read it. so all side on a straight would be 60+60+60 which equals 180 so 180-60=120.

- anonymous

yes in this case its 120, but say that the angle was 30 instead of 60, then it woudl just be 180-30 which would give u 150...understand that?

- anonymous

yes

- anonymous

perfect!...so u good for this question, or do u have any other questions?

- anonymous

I understand now. Thanks for your help

- anonymous

hi

- anonymous

these kind of questions are questions u have to take step by step you know? u cant jut go at it, without finding basic angles...anyway good luck with ur studies hope i helped u understand,

- anonymous

can anyone tell me if geometric series alternate??

- anonymous

anyone please

- anonymous

http://www.ugrad.math.ubc.ca/coursedoc/math101/notes/series/convergence.html
taht will help u

- anonymous

usually they dont, but there are exceptions

- anonymous

the website explain convergent

- anonymous

so js does not matter??

- anonymous

wat do you mean

- anonymous

i am asking if you could have alternate geometric series

- anonymous

kk wat do u mean by alternate? cuz simply wat geometric series are, are values who keep getting multiplied...

- anonymous

ohhh

- anonymous

i am saying about the sign.. negative .. positive.. does not really matter

- anonymous

http://en.wikipedia.org/wiki/Geometric_progression

- anonymous

yes they can be negative

- anonymous

it rlly doesnt matter

- anonymous

thx

- anonymous

i didn't know that

- anonymous

well glad i could help
