Question

daca s=m+9 m=i+3 s+m+i=45 atunci afla prin metoda grafica s=? m=? i=?

Answer 1

s+m+i=45
s=m+9⇒s=i+3+9⇒s=i+12
m=i+3
i este cel mai mic segment
i   /----/
m/----/+3
s/----/+12
avem trei parti egale
45-(3+12)=30( trei parti egale)
30:3=10( o parte adica i)
m=10+3
m=13
s=10+12
s=22
V:22+13+10=45
