complementary angles are angles that add up to 90° so your answer is C. its the only equation that will let you add the second number and get to 90
Answer: C.... 42+x=90

Why: Because angle A is known as 42degrees while x is unknown. So adding angle A and x will equal the angle 90degrees.

Hope this helps!
