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):

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

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

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:

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

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?

@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!
