Answer:
SAS
Step-by-step explanation:
We can automatically eliminate the HL answer choice, since the given triangles aren't right triangles. The only answer choices that could make sense would be ASA or SAS, but there is no ASA choice, so the answer would be SAS.

Step-by-step explanation:
Since K is at the midpoint of HN then HK = KN = 4x + 5, thus
HN = HK + KN ← substitute values
11x - 11 = 4x + 5 + 4x + 5, that is
11x - 11 = 8x + 10 ( subtract 8x from both sides )
3x - 11 = 10 ( add 11 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Hence
KN = 4x + 5 = (4 × 7) + 5 = 28 + 5 = 33
