answer:

∠B = 70°

step-by-step explanation:

  • as you can see, the angle are alternate exterior angles
  • therefore, they are EQUAL
  • we can set them equal to each and solve for x first

∠A = ∠B

8x + 6 = 4x + 38

4x + 6 = 38

4x = 32

x = 8

  • now, we will plug in x in the expression for B to find B

4(8) + 38

32 + 38

= 70

  • therefore, ∠B = 70° and x = 8
