Answer: 142°

Step-by-step explanation:

∡BAC= 38°

∡BAN= 180°-38° = 142°

Answer:

  • 142 = x

Step-by-step explanation:

We know that:

  • Triangle = 180°

Let's name the missing angle x.

  • 73 + 69 + (180 - x) = 180
  • => 142 + (180 - x) = 180
  • => 322 - x = 180
  • => 322 - 180 = x
  • => 142 = x

Hence, the value of the missing angle is 142°.
