Răspuns:
a) AM = 4.5 cm ; AN = 10.5 cm
B) AM = 6 cm ; AN = 21 cm
Explicație pas cu pas:
a)
d || NP => ΔMNP ≈ ΔABM
BM/MP = AM/MN =>
AM = BM×MN/MP =
= 3.6×6/4.8
= 21.6/4.8
= 4.5 cm
AN = AM + MN = 4.5cm + 6cm = 10.5 cm
b)
BM/MP = AM/MN = 2/5 =>
AM = 2MN/5
= 2×15/5
= 30/5
= 6 cm
AN = AM + MN = 6cm + 15cm = 21 cm
