Answer 1

Answer:

<A = 30

<B = 150

Step-by-step 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
