Question

Construiti un triunghi adc cu perimetrul 24 cm ,ab=60%din bc si 5ac =4bc

Answer 1

mai sigur triunghiul este abc nu adc..
ab=60% din bc=>ab=60/100xbc=>ab=6/10bc care se simplifica cu 2=> ab=3bc/5
ab+bc+ac=24
3bc/5+bc+ac=24
3bc/5+5bc/5+ac=24
8bc/5+ac=24
5ac=4bc=>ac=4bc/5
8bc/5+4bc/5=24
12bc/5=24
12bc=24x5
12bc=120
bc=120/12
bc=10
daca bc=10=>ab=3x10/5=>ab=30/5=>ab=6
         bc=10=>ac=4x10/5=>ac=40/5=>ac=8
