Short answer <2 and <3
Explanation
<4 is an interior angle. It has a supplementary angle in <1 which is the easiest to see. It also has another angle that is equal to it in number <5. <1 = <5 because they are vertically opposite angles. But the one that easier to see is <1.
That being said, the remote interior angles are the two interior angles that are not directly connected to <1. That is the remote part. Interior angles are those that are inside the triangle. That can only be <2 and <3.
The answer is <2 and <3 <<<< answer
