Question

5. If △RST ∼△EFG, SH is an altitude of △RST, FJ is an altitude of△EFG, ST = 6, SH = 5, and FJ = 7, find FG

Answer 1

8.4

Explanation:

In similar triangles, corresponding measures are proportional.

FG/FJ = ST/SH

FG = FJ×ST/SH = 7×6/5 . . . . solve for FG, put in given values

FG = 8.4
