Becouse k and n are 'neighbours' so their sum are 180
so k=180-42=138
Do you know your trig ratios?
The congruence theorem that can be used is: B. ASA
<h3>What is the ASA Congruence Theorem?</h3>
If we have two triangles that have two pairs of corresponding congruent angles (e.g. ∠LGH ≅ ∠HKJ and ∠LHG ≅ ∠KHJ), and a pair of corresponding congruent sides (e.g. GH ≅ HK), the triangles are said to be congruent triangles by the ASA congruence theorem.
Therefore, triangles GHL and KHL in the image given are congruent triangles by the ASA congruence theorem.

8$ If the sale is 75% then it would be 8$ because 2x4 is 8 and 3/4 of the is 2.
I think the answer would be 36.5. I divided 4.38 by .12
