Question

Fie trapezul dreptunghic de mai sus in care BM perpendicular CD .Folosind datele din figura obtinem:
BM=... cm
DM=... cm
MC=... cm
DC=... cm

Answer 1

1. BM=AD=3cm

2. DM=AB=2cm

3. MC - aplicam teorema lui Pitagora

$BC^{2}$=$MC{2}$+$BM^{2}$

25=$MC^{2}$+9

$MC^{2}$=16

MC=4

4. DC= DM+MC=2+4=6 cm

Answer 2

BM = AD = 3cm

DM = AB = 2cm

MC = 4cm ( BMC - triunghi pitagoreic)

DC = DM + MC = 4 + 2 = 6cm
