Answer:
x = 15 , ∠ B = 108°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent
∠ A = ∠ B , that is
6x + 18 = x + 93 ( subtract x from both sides )
5x + 18 = 93 ( subtract 18 from both sides )
5x = 75 ( divide both sides by 5 )
x = 15
Then
∠ B = x + 93 = 15 + 93 = 108°
