Question

Exercitiul 6 Va rog dau coroana

Answer 1

Explicație pas cu pas:

a)

AM/MB=1/3⇒MB=3*AM

AB=AM+MB=12⇒AM+3*AM=12⇒4*AM=12⇒AM=3(cm)

MB=3*3=9(cm)

b)

AM/MB=2⇒AM=2*MB

AM+MB=12⇒3*MB=12⇒MB=4(cm)

AM=2*4=8(cm)

c)

MB/AB=5/6⇒MB=5/6*AB

MB+AM=12⇒5/6*12+AM=12⇒AM=12-10⇒AM=2(cm)

MB=5/6*12=10(cm)

d)

2*MB=3*AM⇒MB/AM=3/2⇒MB=3/2*AM

AM+MB=12⇒AM+3/2*AM=12⇒5*AM=24⇒AM=24/5

MB=3/2*24/5=72/10
