Question

$\triangle kji \cong \triangle pqr$. what is $qr$? _______ inches

Explanation:

Step1: Match congruent triangle sides

First, confirm corresponding parts of congruent triangles: $\triangle KJI \cong \triangle PQR$, so side $JI$ corresponds to $QR$.

Step2: Verify side length of $JI$

From $\triangle KJI$, the length of $JI$ is 87 inches. Since corresponding sides of congruent triangles are equal, $QR = JI$.

Answer:

87 inches
