In the figure, ∠1 ≅ ∠2, ∠3 ≅ ∠4, and . you can justify the conclusion that ∠tkl ≅ ∠tlk by stating that complements of congruent angles are congruent. the sas postulate. the hl theorem. that supplements of congruent angles are congruent.

From the question, we know that we will be looking at <3, <4, and angles TKL and TLK. That being said, since <3 is congruent to <4, that means that angles TKL and TLK, which are each supplementary to either angle 3 or 4, are congruent because, since angles 3 and 4 are congruent, they are congruent because the supplements of congruent angles are congruent.

Y=-2x-6 is the answer
