Answer:

∠ B = 126°

Step-by-step explanation:

Since the lines are parallel, then

∠ A = ∠ B ( alternate angles ), thus

8x + 78 = 2x + 114 ( subtract 2x from both sides )

6x + 78 = 114 ( subtract 78 from both sides )

6x = 36 ( divide both sides by 6 )

x = 6

Thus

∠ B = 2x + 114 = 2(6) + 114 = 12 + 114 = 126°
