Answer:
b=7
Step-by-step explanation:
2(3b-1)= 40
divide both sides by 2
3b-1 = 20
then add 1 to each side
3b = 21
then divide both sides by 3
b = 7
then check 2(3*7-1) = 40
Answer:
Step-by-step explanation:
∠2= ∠4 { alternate interior angles}
∠2= 65
∠1 + ∠2 = 180 {linear pair}
∠1 + 65 = 180
∠1 = 180- 65
∠1 = 115
