Answer:
adjacent
Step-by-step explanation:
Complementary angles add up to 90 degrees. These two do not. So they are not complementary.
Linear means they add up to 180o. (Same as supplementary). These two do not meet those conditions.
vertical angles are across from each other when two line segments or lines cross. These two do not.
The answer is adjacent. 90 <a+b<180
