Question

△klm ≅ △qrs. what is m∠k?

Explanation:

Step1: Recall congruent - triangle property

Corresponding angles of congruent triangles are equal. Since $\triangle KLM\cong\triangle QRS$, $\angle K$ corresponds to $\angle Q$.

Step2: Identify $\angle Q$'s measure

From $\triangle QRS$, $m\angle Q = 43^{\circ}$.

Answer:

$43$
