Question

Daca triunghiull abc este asemenea cu triunghiul def, ab=8 de=6 df=12 ef=9 calculati ac si bc

Answer 1

$Folosim- teorema - asemanarii \\ \frac{AB}{DE} = \frac{AC}{DF} = \frac{BC}{EF} \\ \\ \frac{8}{6} = \frac{AC}{12} = \frac{BC}{9} \\ \\ AC= \frac{8*12}{6} =16 \\ \\ BC= \frac{16*9}{12} =12$
