Answer:
See explanation
Step-by-step explanation:
16. Two parallel lines are cut by transversal. Angles with measures and are alternate exterior angles. By alternate exterior angles, the measures of alternate exterior angles are the same:
Then
17. Two parallel lines are cut by transversal. Angles with measures and are alternate interior angles. By alternate interior angles, the measures of alternate interior angles are the same:
Then
18. Two parallel lines are cut by transversal. Angles with measures and are alternate exterior angles. By alternate interior angles, the measures of alternate exterior angles are the same:
Then
19. The diagram shows two complementary angles with measures and . The measures of complementary angles add up to then
Hence,
Check:
20. Angles and are vertical angles. By vertical angles theorem, vertical angles are congruent, so
Hence,
21. and are supplementary. The measures of supplementary angles add up to so
Therefore,
(n - 2)*180
Therefore, (8 - 2)*180
Which equals to 6(180) or 1080
