I appreciate your efforts, Lookagain. However....
1) the problem as stated doesn't tell us ANYTHING about how the angles are related.
I could ASSUME what you did, and come to the same conclusion. But I hate to assume anything.
If you want to do that, then at least I think you should specify the conditions you're assuming to
reach your conclusion.
For example, I'd say "IF m<MKL + m<JKL = m<MKJ, then...
2) and substitute (PLUG IN????) the expressions given.
I can plug in my toaster....but there's no "plug in" property in mathematics that I know of.
3) Please contact me by private message if you want to continue this discussion further.
Shakur1997,
1) I made a wrong assumption that yours was the only scenario.
There are two sets of angles for the answers. It can also be this:
m<MKL + m<MKJ = m>JKL ===>
(2x + 6) + 62 = 10x - 4
2x + 68 = 10x - 4
72 = 8x
9 = x
x = 9
Then m< MKL = 2(9) + 6 = 24
And m>JKL = 10(9) - 4 = 90 - 4 = 86
The other set of angles comes from your assumed scenario.
2) Thousands of sources and authors have used "plug in" to mean "insert."
Here's a portion from this source:
http://www.freemathhelp.com/functions.html
---------------------------------------------------------------------------------
"To evaluate a function means to pick different values for the input (often named x)
in order to find the output (often named y). In terms of evaluation, for every choice
of x that you pick, only
one corresponding value of y will be the end result. You'll
often be directed to evaluate a particular function for a certain value of x.
That means just
> > plug in
< < that value for x and see what
you get, like below:
Evaluate for x=2:
y = 4*x - 7
Solution:
We have our function already solved for y, and we need to just
> > plug in x=2
< <
to evaluate the function at that point.
y = 4*2 - 7
y = 8 - 7
y = 1
-------------------------------------------------------------------------------
However, in the online dictionaries, I couldn't find one that stated that "plug in"
could be used a "substitute in." I will try not to use that.
3) Shakur1997,
you and I are having the discussion
here.
