Answer:

  • 22°

Step-by-step explanation:

Refer to picture

Added angles a and b as interior angles of same triangle with angle x to make solving simple.

Angle a is same as 42° since both angles intercept same arc AB.

  • a = 42°

Angle b is supplementary with 64° angle as linear pair

  • b = 180° - 64° = 116°

Some of the interior angles of a triangle is 180

  • x + 42° + 116° = 180°
  • x + 158° = 180°
  • x = 180° - 158°
  • x = 22°
