Daca se imparte lungimea laturii mijlocii la lungimea celei mai mici dintre laturi se obtine catul 1 si restul 25 Afla lungimea celor trei laturi ale triunghiului

Answer 1

 metoda grfica
C |----| A |----|----|+8
B |----|+25 
225-(25+8)=192 192:4=48 (c) (48×2)+8=104 (a) 48+25=73 (b)
 \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\a-latura mare
b-latura mijlocie
c-latura mica
a+b+c=225cm 
a:c=2 r=8=>a=2c+8
b:c=1 r=25 =>b = c+25 
2c+8+c+25+c=225cm
4c+33cm=225cm 
4c= 225cm+33cmy
4c=192
c=48 cm 
b= 48 cm + 25 cm 
b= 73 cm 
a = 2x48cm+8cm 
a=96 cm +8 cm
a=104 cm
