Answer:

$x=30^{\circ}$

Step-by-step explanation:

Looking at $\triangle LMN$ :

$\angle NML = 180 - (90+45)$ (angle sum of triangle is $180^{\circ}$ )

$=45^{\circ}$

Looking at $\triangle KNM$ :

$\angle KNM = 180-105$ (angle of straight is $180^{\circ}$ )

$=75^{\circ}$

$\angle KNM + \angle NKM + \angle KMN = 180$ (angle sum of triangle is $180^{\circ$ )

$75+2x+45 = 180$

$2x+120 = 180$

$2x=60$

$x=30^{\circ}$

Hope this helps :)

The midpoint formula is:
(point1 + point2)/2

1) (-2 + 12)/2 = 5

2) (-1 +5)/2 = 2
    (0+2)/2 = 1
     (2,1)

3) Sqrt of (x2-x1)^2 + (y2 - y1)^2
     sqrt of (7 -1)^2 + (-7 - 1)^2
     sqrt of (6)^2 + (-8)^2
     sqrt of 36 + 64
     sqrt of 100
     10

Hope this helps!
