Question

I need help with #63

Answer 1

Step-by-step explanation:

Given that line a is parallel to line b

∠6 = ∠2 = 36.5° (property of corresponding angles)

∠8 = 180° -∠6 (property of adjacent angles on a straight line)

∠8 = 180° - 36.5° = 143.5°  

Answer 2

2 and 6 are Corresponding angles
So, 2= 6=36.5 degrees
6+ 8=180 degrees
8=180-36.5=143.5 degrees
