Answer:
56 degrees
Step-by-step explanation:
If an inscribed triangle has its hypotenuse as the diameter, we can conclude that the angle opposite the hypotenuse (angle GHI) is 90 degrees.
Now, we know two angles of the triangle. Using algebra and the fact that the sum of angles in a triangle is 180 degrees, we can see that the measure of angle G is 180-90-34 = 56 degrees.
