Answer:

  115

Step-by-step explanation:

The measure of x is half the sum of the intercepted arcs. The arc on the left is a semicircle, so 180°.

The arc on the right is the difference between 180° and the two arcs shown, 60° and 70°, so is 180° -60° -70° = 50°.

Then half the sum of the intercepted arcs is ...

  x° = (180° +50°)/2 = 230°/2 = 115°

  x = 115
