Answer:

  x = 11

Step-by-step explanation:

The external angle is half the difference of the subtended arcs. The smaller arc is shown as 86°. The larger arc will be the difference between 360° and the two arcs shown.

  larger arc = 360° -74° -86° = 200°

So, the external angle is ...

  4x +13 = (200 -86)/2 = 57

  4x = 44 . . . . . . . . . . . . subtract 13 from both sides

  x = 11 . . . . . . . divide by 4
