Answer:

Question 1

  • h = 56° as alternate interior angles (the diameter is the transversal)
  • f = 90° as opposite to the diameter
  • g = 90° - 56° = 34° as complementary angle in right triangle

Question 2

  • i = 65° as the same arc is intercepted
  • i + j = 90° as opposite to diameter
  • j = 90° - i = 90° - 65° = 25°
