If these angles combine together to form a straight line, then angle two must add to 180 with angle one. In this circumstance, angle two has to be 140. It's also this way concerning opposite exterior or interior angles, as well as corresponding angles. If angle two is vertical to angle one, it is 40. Without seeing the angles, this is all I can really give you. Hope I helped!
Since b is the midpoint BC is half the line so we can set up this equation
x+4+X+4=3x-8
and then solve like normal
2x+8=3x-8
16=x
once you have x then solve x+4
16 + 4 =20
AB is 20
Divide the y-value by the x-value.
(1/2) / (2/5) = 1/2 x 5/2 = 5/4
