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
D
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
