Answer:

<A = 30

<B = 150

Explanation:

  • cos<A = AK / AB
  • AK = 4
  • AB = 8
  • Cos<A = 4/8
  • Cos<A = 1/2
  • A = Cos-1(0.5)
  • A = 30 degrees
  • Since BC and and AD are parallel, the interior angles of <A and <B sre supplementary.
  • <A + <B = 180
  • 30 + <B = 180
  • <B = 180 - 30
  • <B = 150
