I didn’t understand so I need a help

y is 107° and z is 36°

Step-by-step explanation:

73° and y are supplementary angles so they add up to 180°

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

divide the numbers

step-by-step explanation:

your answer is option c.
