Answer:
y = 107
z = 36
Step-by-step explanation:
We are given that line o is parallel to line m, and we can notice line k is a transversal through them both. Using same side interior angles, we can say that:
y + 73 = 180
and
y = 107
Next, using vertical angles, we can say that:
5z - 73 = y
We already have y = 107, so we can substitute that in:
5z - 73 = 107
5z = 180
z = 36
