Answer:

  s = 2°

Step-by-step explanation:

The triangle sum theorem tells you the sum of angles in a triangle is 180°. This fact can be used to write an equation that can be solved for s.

  s +38° +34s +72° = 180°

  35s = 70° . . . . . . . . . . . . . subtract 110°

  s = 2° . . . . . . . . . . . . . divide by 35

Check

The triangle angle measures are (s+38°) = 40°, 34s = 68°, and 72°. These total 180°, as they should.
