Explicație pas cu pas:
Folosind T Inaltimii
AD²=BM×MC 144=x(25-x) x²-25x+144=0 cu solutiile
x1=16 cm si x2=9 cm
BM+MC=BC
1)
BM=16 cm CM=13cm
Teorema catetei
AB²=BM×BC AB²=16×25 ⇒AB=20 cm
AC=BC×AD/AB AC=25×12/20=15 cm
P=25+20+15=60 cm
2) BM=9
AB²=9×25 AB=3×5=15 cm
AC=AD×BC/AB=12×25/15=20 cm
P=25+15+20=60 cm
