what does B equal ? please help me

Answer:
108
Step-by-step explanation:
These are alternate exterior angles and alternate exterior angles are equal when the lines are parallel
A = B
6x+18 = x+93
Subtract x from each side
6x+18 -x = x+93-x
5x +18 = 93
Subtract 18 from each side
5x + 18-18 = 93-18
5x =75
Divide by 5
5x/5 = 75/5
x = 15
Angle B
x+93
15+93
108
Answer:
Solution given:
<A+<B=180°[ alternate exterior angle are equal]
6x+18=x+93
6x-x=93-18
5x= 75
x=15
now
<B=15+93=108°
