Answer:
The answer to your question is below
Step-by-step explanation:
Data
∠1 = 105°
Process
a)
∠2 = 180 - 105 = 75° supplementary angles
∠3 = ∠2 = 75° supplementary angles
∠4 = 105° vertical angles
∠5 = 105° corresponding angles
∠6 = 180 - 105 = 75° alternate interior angles
∠7 = ∠6 = 75° supplementary angles
∠8 = 105° alternate interior angles
b)
∠3 = 80°
∠1 = 180 - 80 = 100° supplementary angles
∠2 = 80° vertical angles
∠4 = 100° supplementary angles
∠5 = 100° supplementary angles
∠6 = 80° alternate interior angles
∠7 = 80° corresponding angles
∠8 = 100° supplementary angles
