Explicație pas cu pas:
a) N apartine lui MK
MK=4,4cm
NK=26mm
___________
MK=?
REZOLVARE:
26mm=2,6cm
MK=MN+NK
MN=MK-NK
MN=4,4-2,6
MN=1,8cm
b)N apartine lui MK
MK=6,3cm
MN=17mm
___________
NK=?
REZOLVARE:
6,3cm=63mm
NK=MK+MN
NK=17+63
NK=80mm
c)N apartine lui MK
KN=5,6cm
MN=0,9dm
___________
MK=?
REZOLVARE:
0,9dm=90cm
MK=KN+MN
MK=90+5,6
MK=95,6cm
