Question

va rog frumos ¡¡¡!!!!​

Answer 1

Răspuns:

a si b sunt catetele,iar c este ipotenuza

{a,b} D.P. {0,(6);0,5}

{a,b} D.P. {2/3;1/2}

a/2/3=b/1/2

b×2/3=a×1/2

2×2b=3a

4b=3a

3a-b/2=14

4b-b/2=14

8b-b=14×2

7b=14×2

b=4

a=4×4/3=16/3

din teorema lui pitagora:

a²+b²=c²

4²+(16/3)²=16×9/9+16×16/9=

=16/9(16+9)=c²

c²=16×25/9

c=4×5/3

c=20/3

P=a+b+c=16/3+4+20/3

=(16+12+20)/3=

=48/3=16cm
