Fie segmentul [AB] cu lungimea de 5 cm Desenati M E AB astfel incat
AM/AB=1,5
şi deaminaţi lungimea segmentului (MB).

Answer 1

M E AB => AM+MB=AB

AM+MB=5

AM/AB=1,5

AM/AM+MB=1,5=> AM+MB=1,5AM

=>AB=1,5AM=> 5=1,5AM=> AM=5/1,5

1,5=15/10=3/2

AM=5:3/2=5×2/3=10/3

AM+MB=5=> 10/3+MB=5=> MB=5-10/3

MB=(15-10)/3

MB=5/3
