4.

Once is opposite to , they are the same. It is the same for , equals to 40º.

m∠y = 40º

The ∠x and 40º are supplementary, therefore ∠x = 140º.

∠z = 140º

m∠x = 140º

m∠y = 40º

m∠z = 140º

5.

Considering the explanation from the question 4:

m∠x = 50º

m∠y = 130º

m∠z = 50º

just needed some points but try socratic

the two may have that, even a breakdown is probably offered
