List the sides from shortest to longest?

OpenStudy (icalibear):

m<A = 8x+ 2 m<B = 2x - 8 m<C = 94 -4x Shortest to longest ____________

OpenStudy (compassionate):

C B A

OpenStudy (compassionate):

I may be wrong, depending on what we're talking about.

OpenStudy (icalibear):

(a) AC; AB, BC (b) AC; BC; AB (c) AB; AC; BC (d) AC; BC, AB

OpenStudy (icalibear):

theyre just sides of a triangle

OpenStudy (compassionate):

Oops, yea, I was wrong. Can't help you with this one. Try Yahoo Answers.

OpenStudy (anonymous):

first find the value of x. Sum of all angles of a triangle =180 m<A + m<B + m<C=180

OpenStudy (anonymous):

can u?

OpenStudy (icalibear):

how would that be set up to find x whats the equation

OpenStudy (anonymous):

Sum of all angles of a triangle =180 m<A + m<B + m<C=180 8x+2 + 2x-8 + 94-x =180

OpenStudy (anonymous):

Now find x can u?

OpenStudy (icalibear):

yep just a min

OpenStudy (icalibear):

i got... 20.9.. i dont know how..

OpenStudy (anonymous):

8x+2 + 2x-8 + 94-x =180 9x -88 =180 9x = 268 x=268/9

OpenStudy (icalibear):

29.7

OpenStudy (anonymous):

now, substitute x = 29.7 and find m<A , m<B and m<C

OpenStudy (anonymous):

can u?

OpenStudy (icalibear):

yep

OpenStudy (anonymous):

So, what are the values of m<A , m<B and m<C

OpenStudy (icalibear):

hold on my calc isnt working D:

OpenStudy (icalibear):

237.6 + 2, 59.4 - 8, and 64.3

OpenStudy (anonymous):

I dont think that is right

OpenStudy (icalibear):

well what did you get?

OpenStudy (anonymous):

8x+2 + 2x-8 + 94-x =180 9x+88=180 9x =92 x=10.2

OpenStudy (anonymous):

x is not 29.7 it is 10.2

OpenStudy (anonymous):

Now, use it to find m<A ,m<B and m<C

OpenStudy (icalibear):

ok

OpenStudy (anonymous):

what did u get?

OpenStudy (icalibear):

ok i got it sorry i got: 88.1 + 12.4 + 83.8 = 180

OpenStudy (icalibear):

is that right?

OpenStudy (icalibear):

@sauravshakya

OpenStudy (anonymous):

m<A = 8* 10.2 +2 =82.6 m<B =12.4 m<C=53.2

OpenStudy (icalibear):

so its A, C, B but they want line segments or something

OpenStudy (anonymous):

So, m<B , m<C , m<A AC , AB ,BC

OpenStudy (icalibear):

oh ok. thanks!
