se considera punctele coliniare A,B,C astfel incat AB/BC=5/3 si AC=16cm. determinati lunginea segmentelor AB si BC. repede va rog frumoss.... (/=inseamna supra )
AB inseamna 5 parti iar BC inseamna 3 parti in total de la A la C=16cm AB+BC=AC 5parti+3parti=16cm 8parti=16cm 1parte = 16cm:8=2cm (parte sau segment, cum vrei s-o iei) deci AB=5X2cm=10cm si BC=3x2cm=6cm PROBA.....AC=10cm+6cm=16cm SUCCES!
