By solving a system of equations, we will see that m measures 12 units.
<h3>
How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.

3 hours because 39 divided by 13 equals 3 and to check just do 13x3 and it will get you to 39. in conclusion edgar will have to do 3 hours of hard work to get $39
Answer:Do rise over run, maybe watch a tutorial on it, pretty simple method
You have a lot of questions here, try breaking them up into multiple posts and you may get more responses.
I will help with some.
<span>(x+3)=0
The solution is just -3.
-----------------------------------------------------------------
3m(m-4)=0
The two solutions are 0 and 4.
-----------------------------------------------------------------
(r-3)(r+2)=0
The two solutions are and 3 and -2.
