Question

Ajutor, repede plss ​

Answer 1

Explicație pas cu pas:

a)

$AM = MC => AC = 2×MC \\ CN = NB => CB = 2×CN$

$AB = AC + CB = 2×MC + 2×CN = 2(MC + CN) = 2 \times MN$

$=> MN = \frac{1}{2} AB$

b)

$AM = MC = \frac{AC}{2} = \frac{10}{2} = 5 cm$

$CB = AB - AC = 16 - 10 = 6 cm$

$CN = \frac{CB}{2} = \frac{6}{2} = 3 cm$

distanta:

$d = \frac{AM}{2} + MC + \frac{CN}{2} = \frac{5}{2} + 5 + \frac{3}{2} = \frac{8}{2} + 5 = 4 + 5 = 9 cm$
