Answer:
y = 94
z = 77
Step-by-step explanation:
Since the angle z is supplementary to 103, we can say that.
z + 103 = 180
Solving for z, we get that z = 77.
Now, to solve for y, we need to recall the fact that the internal angles in a quadrilateral always add up to 360. We know 3 of the angles, so we can set up an equation:
y+77+106+83 = 360
y+266 = 360
y = 94
