Answer:

30°

Step-by-step explanation:

[tex]\frac{195-(8x+17)}{2}=5x-10 \\ \\ 178-8x=10x-20 \\ \\ 198=18x \\ \\ x=11[/tex]

So, this means arc FH measures 105 degrees.

Since the circumference of a circle measures 360 degrees, arc EF measures 60 degrees.

By the inscribed angle theorem, angle EHF measures 30°.
