Answer 1

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
