Answer:
If angle dgf as an angle of 108
that means that the equation would look like this x + 4x-2=108
= 5x-2=108
then you solve for x
5x=110
110/5 = 22 = x
hope that answers your question

Answer:
2x + 20 = 3x-10
2x -3x = -20-10
-x = -30
x= 30
Checking part: 
2x+20 = 2(30) +20 = 60+20 = 80
3x-10 = 3(30) - 10 = 90-10 = 80
Hence, the final answer is x = 30.

For 

 the function is undefined.

So, the limit doesn't exist.

Consider two points in a two dimensional coordinate plane 

As you know mid point of a line joining two points is the coordinate of the middle point of only that portion of line joining between two points.
[tex]\text   { Mid point of  }  (x_{1},y_{1})\text { and }  (x_{2},y_{2}) =(\frac{x_{1}+x_{2}}{2} ,\frac{y_{1}+y_{2}}{2})[/tex]
As we know distance formula gives the Distance between line joining two points in two dimensional coordinate system.It is always positive.
[tex]\text   { Distance formula between two points  }  (x_{1},y_{1})\text { and }  (x_{2},y_{2}) =\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
Distance formula gives the distance between two points, whereas Mid point formula gives coordinate of the middle point.
