Answer:

70

Step-by-step explanation:

x=8

8x+6=4x+38

8x-4x

4x+6=38

4x=32

x=8

Solution :

  • <A=<B (alternate exterior angles)
  • Thus,
  • 8x+6=4x+38
  • 8x-4x=38-6
  • 4x=32
  • x= 32/4
  • x= 8°

Thus , x = 8°

But , we need to find < B , so

= <B = 4x+38°

= <B = 4×8+38 = 70°

Thus , our answer is 70°
