Question

Susan is standing in front of a tree at point S. She can see an arc of the tree trunk that stretches from J to K measuring 138°. What is the measure of angle JSK?

Answer 1

trig?

Answer 2

geometry

Answer 3

how tall is the tree?

Answer 4

it doesn't say..

Answer 5

my answer choices are

42°

69°

138°

111°

Answer 6

like i think its a triangle just look at it that way but im then not exactly sure how to find each angle..

Answer 7

were looking for angle JSK, just not sure how to find it.

Answer 8

180-138=42 I think that is the answer...

Answer 9

:) true. i get where you are coming from, just seems a little easy i guess but ill try it. tnx. Ill give u a medal once i check it.

Answer 10

was it right?

Answer 11

ah, haven't checked yet, but im thinking it is. I have 5 more problems to do, so didn't really want to wait because i might have to go onto other questions..

Answer 12

ill post it back here and bump it when im done though.

Answer 13

k, by the way do you know how to factor cubic functions?

Answer 14

hmm, depends. Show me a problem.

Answer 15

"Identify all the roots:
f(x)=2x^3+x^2-61x+30

Answer 16

hmm, what math is this?

Answer 17

alg 2

Answer 18

oh ok. wait are there any other instructions and do u have answers?

Answer 19

I have a key that my teacher posted, but im trying to study for my final, which is tomorrow ;(

Answer 20

oh ok. Thats cool, had my final like 2 weeks ago, got an A. im just.. not really remembering finding the roots of an F(X) problem... with f(x)'s.. we just solved them.. if you showed me an example or something im sure i could do it though, im great with algebra.

Answer 21

like.. am i factoring this or i think i might remember but i need a hint.. its summer.. tend to forget..

Answer 22

I think finding the factors of d in ax^3+bx^2+cx+d, then plugging them in to make it equal 0

Answer 23

refer to the problem i already posted

Answer 24

so im finding the factors of the fx equations numbers and then plugging them in to make it =0?

Answer 25

as a check..

Answer 26

hard to explain...

I just cant figure it out

Answer 27

lme look..

Answer 28

oh ok i know this.. let me just refresh myself on the last part..

Answer 29

my brain is fried... I cant think or remember anything
on top of that, I have two other finals

Answer 30

i understand.. alright.. just 1 more question.. so i know what this is.. but what do you need as an answer? when i did this my answers were not equations but.. i forget what you call something not an equation..

Answer 31

apparently x=1/2 is one root, but i don't understand how my teacher got it

Answer 32

u mean a factor?

Answer 33

well... im factoring to get the roots

Answer 34

hmm, 1 sec.. then..

Answer 35

why don't we close this and ill ask a new question?

Answer 36

alright. i don't think ill answer though as im looking at it.. maybe this.. http://www.sosmath.com/algebra/factor/fac02/fac02.html but i don't think i get it or my brain is also fried from doing so much online math today..

Answer 37

k, my question is at top

Answer 38

im sorry. though i dont think i did this.. i know..good luck though!.
