Answer:
Part 1) [tex]m<8=42\°[/tex]
Part 2) [tex]m<8=30\°[/tex]
Step-by-step explanation:
Part 1) What is the measure angle 8?
we have
[tex]m<1=42\°[/tex]
we know that
[tex]m<1=m<8[/tex] ------> by alternate exterior angles
therefore
[tex]m<8=42\°[/tex]
Part 2) What is the measure angle 8?
we have
[tex]m<4=30\°[/tex]
we know that
[tex]m<4=m<8[/tex] ------> by corresponding angles
therefore
[tex]m<8=30\°[/tex]
