Answer 1

Step-by-step explanation:

1. x + 74 = 180 [ linear pair ]

=> x = 180 - 74

= 106

2. 4x + x = 180 ( linear pair )

= 5x = 18p

=> x = 180/5

x = 36

3. Yes these lines are parallel because the pair of adjacent sides is equal to 180° i.e 132 + 48 = 180

4.Yes these lines are parallel because alt. exterior angle add up to 180 °
