Answer:

Step-by-step explanation:

1. Arc DFG and arc DHG complete the circle. The measure of arc DHG is 90° +38° = 128°, so the measure of arc DFG is ...

  360° -128° = 232° = mDFG

__

2. Arc GHE is 180°. Arc HE is 38° less than that value, so is ...

  mHE = 180° -38°

  mHE = 142°

__

3. The angle at H is half the difference of the intercepted arcs:

  H = (100° -32°)/2 = 68°/2

  H = 34°
