Answer:

none of the above

Step-by-step explanation:

Vertical angles are opposite angles made by intersecting lines

 a and b are not vertical angles  no

Complementary angles - two angles  that add to 90 degrees

b is 90 degrees by itself  no

Supplementary angles - two angles that add to 180 ( would make a straight line)

a and b do not form a straight line  they are not vertical angles - no

Answer:

D

Step-by-step explanation:

Complementary angles add up to 90 and Supplementary angles add up to 180

90 < a + b < 180

So, neither complementary nor Supplementary

Clearly they aren't vertical angles either
