Answer:
∠3 and ∠4
Step-by-step explanation:
What are Adjacent Angles?
Two angles are said to be adjacent angles when they share a common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle
In this diagram, the adjacent angles are ∠3 and ∠4
They lie on the same side and next to each other.
Specifically since these angles are formed by the intersection of one ray with the other ray, they are supplementary angles - the sum of their measures is 180°
