Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.
An outside angle is equal to the sum of the two opposite inside angles.
The two opposite inside angles from X are 63 and 46.
X = 63 + 46 = 109 degrees.
