Answer 2

15.......................

• Consecutive interior angles

16........................

• Corresponding angles

17........................

• Alternate interior angles

18........................

• Vertical angles

19........................

• m∠2 + m∠3 = 180
• 8x - 20 + 5x + 5 = 180 ⇒ 13x = 195 ⇒ x = 15
• m∠2 = 8*15 - 20 = 100°
• m∠3 = 5*15 + 5 = 80°

20........................

• m∠1 = m∠7 = m∠3 = m∠5 = 80°
• m∠2 = m∠8 = m∠4 = m∠6 = 100°
