Question

In triunghiul MNP,AB paralel cu MN,A apartine segmentului MP si B apartine segmentului NP.Stiind ca AM=3,AP=9,NB=2,AB=12.​Aflati MP,BP,NP,MN.

Answer 1

Răspuns:

Explicație pas cu pas:

MP=AM+AP=3+9=12 cm

AP/MP=PB/PN=AB/MN

9/12=PB/PB+NP

9/12 =PB+2

12PB=9(PB+2)

12PB=9PB+18

3PB=18

PB=6 cm

NP=PB+NB=6+2=8 cm

PB/PN=AB/MN

6/8=12/MN

MN=8*12/6 =16 cm
