Find the perimeter of the given triangle.

1. △JKL, if △JKL ~ △RST, RS = 14, ST =12, TR = 10, 2. △DEF, if △DEF ~ △ABC, AB = 27, BC = 16, CA = 25,
and LJ = 14 and FD = 15

3. △PQR, if △PQR ~ △LMN, LM = 16, MN = 14, 4. △KLM, if △KLM ~ FGH, FG = 30, GH = 38, HF = 38,
NL = 27, and RP = 18 and KL = 24.

Use the given information to find each measure.

5. Find FG if △RST ~ △EFG, SH is an altitude of 6. Find MN if △ABC ~ △MNP, AD is an altitude of
△RST, FJ is an altitude of △EFG, ST = 6, SH = 5, △ABC, MQ is an altitude of △MNP, AB = 24,
and FJ = 7. AD = 14, and MQ = 10.5.
