Question

Consider triangle JKL. Given that triangle JKL - triangle PKQ, if JK = 8, PK = 4, and PQ = 5, what is the length of JL? A. 2.5. B. 5. C. 10. D. 8.5.

Answer 1

Since the similarity order matches vertices (J↔P, K↔K, L↔Q), corresponding sides give JK/PK = JL/PQ. So JL = PQ·(JK/PK) = 5·(8/4) = 10.

Answer: C. 10.
