1 answer:
Answer:
Step-by-step explanation:
Vertically opposite angles are equal.
m∠2 = m∠1
20x - 14 = 17x + 1
Add 14 to both sides
20x = 17x + 1 + 14
20x = 17x + 15
Subtract 17x from both side
20x - 17x = 15
3x = 15
Divide both sides by 3
x = 15/3
x = 5
∠1 = 17x + 1 = 17*5 + 1 = 85 + 1 = 86
∠2 = 20x - 14 = 20*5 - 14 = 100 - 14 =86
