In similar figures corresponding sides are proportional. [tex] \frac{JF}{TF} = \frac{YP}{AP} [/tex] Looking at the Name Quad. RJFT ~ Quad. SYPA Side JF corresponds to Side YP Side TF corresponds to Side AP
Put in the numbers: [tex] \frac{60}{s} = \frac{25}{40} [/tex] Cross multiply to solve (used "s" for the unknown side TF: 25s = 60 × 40 25s = 2400 s = 96 TF = 96
