Two angles are complementary if their measures add up to 90 degrees. Looking at the given measures, we can see that 120 and 17 add up to 137, which is not 90. Similarly, 73 and 34 add up to 107, which is also not 90. However, 73 and 17 do add up to 90 degrees, so those are the two angle measures that correspond to complementary angles. Therefore, the correct answer is: 73 and 17.
