Use substitution
3x = 2(-6x + 18) + 14
3x = -12x + 36 + 14
3x = -12x + 50
15x = 50, x = 50/15 = 10/3
Solution: x = 10/3
<h2>Hello!</h2>
The answer is:
The coordinates of the midpoint are:

<h2>
Why?</h2>
We can find the midpoint of the segment with the given endpoints using the following formula.
The midpoint of a segment is given by:

We are given the points:

and

Where,

So, calculating the midpoint, we have:



Hence, we have that the coordinates of the midpoint are:

Have a nice day!
Answer:
M= 15 degrees N= 15 degrees
Step-by-step explanation:
Right triangles are always 90 degrees so 90-60=30
since theres 2 sides you have to split 30 in 2 so 30 divided by 2 equals 15
