Answer:
[tex]m\angle 1=m\angle 3=m\angle 5=m\angle 7=131^{\circ}[/tex]
[tex]m\angle 2=m\angle 4=m\angle 6=m\angle 8=49^{\circ}[/tex]
[tex]m\angle 9=m\angle 11=m\angle 13=m\angle 15=92^{\circ}[/tex]
[tex]m\angle 10=m\angle 12=m\angle 14=m\angle 16=88^{\circ}[/tex]
Step-by-step explanation:
1.
Angles 7 and 5 are corresponding, then
[tex]m\angle 5=m\angle 7=131^{\circ}[/tex]
Angles 7 and 2 are supplementary, then
[tex]m\angle 2=180^{\circ}-131^{\circ}=49^{\circ}[/tex]
Angles 1 and 7 are vertical, so
[tex]m\angle 1=m\angle 7=131^{\circ}[/tex]
Angles 2 and 8 are vertical, so
[tex]m\angle 2=m\angle 8=49^{\circ}[/tex]
Angles 2 and 4 are corresponding, then
[tex]m\angle 2=m\angle 4=49^{\circ}[/tex]
Angles 1 and 3 are corresponding, then
[tex]m\angle 1=m\angle 3=131^{\circ}[/tex]
Angles 8 and 6 are corresponding, then
[tex]m\angle 6=m\angle 8=49^{\circ}[/tex]
Thus,
[tex]m\angle 1=m\angle 3=m\angle 5=m\angle 7=131^{\circ}[/tex]
[tex]m\angle 2=m\angle 4=m\angle 6=m\angle 8=49^{\circ}[/tex]
2.
Angles 16 and 14 are corresponding, then
[tex]m\angle 16=m\angle 14=88^{\circ}[/tex]
Angles 16 and 15 are supplementary, then
[tex]m\angle 15=180^{\circ}-88^{\circ}=92^{\circ}[/tex]
Angles 16 and 10 are vertical, so
[tex]m\angle 10=m\angle 16=88^{\circ}[/tex]
Angles 9 and 15 are vertical, so
[tex]m\angle 9=m\angle 15=92^{\circ}[/tex]
Angles 15 and 13 are corresponding, then
[tex]m\angle 13=m\angle 15=92^{\circ}[/tex]
Angles 10 and 12 are corresponding, then
[tex]m\angle 12=m\angle 10=88^{\circ}[/tex]
Angles 9 and 11 are corresponding, then
[tex]m\angle 9=m\angle 11=92^{\circ}[/tex]
Thus,
[tex]m\angle 9=m\angle 11=m\angle 13=m\angle 15=92^{\circ}[/tex]
[tex]m\angle 10=m\angle 12=m\angle 14=m\angle 16=88^{\circ}[/tex]
