X=62
Vertically opposite angles are equal
Y=44
Angles on a straight line add up to 180
Z =286
Because
180-x-y=74
360-74=286
-3y-8x+3x^2 is the simplified version of 7y+2x-10y+3x^2-10x
Here we want to find the equation of the line containing the median CP.
P, being the midpoint of AB can be found using the midpoint formula as:

.
The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

.
Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

.
