Question

Please help me idk what it's even asking for​

Answer 1

It is asking you what you would put as your statement for step 4.

The answer by the way would be what you have clicked on - angle 1 + angle 4 = 180 degrees.

Answer 2

marked answer is correct

Explanation:

The problem is asking you to choose an equation that should be written as statement 4 of the proof.

Statement 4 is an algebraic expression of the verbal statement 3. The marked response is correct. It expresses the relationship that is the definition of supplementary angles.

Often you can gain a clue in these proofs by looking at places that use similar reasons or similar statements. Lines 5 and 6 are the algebraic and verbal representations of the relation between angles 1 and 2. This matches lines 3 and 4, which are the verbal and algebraic representation of the same relationship between angle 1 anf 4.
