Răspuns :
a)
a = 4K
b = 5K
c = 3K
a patrat + c patrat = (4K) patrat + (3K) patrat = 16 K patrat + 9 K patrat = 25 K patrat = (5K) patrat
a patrat + c patrat = (5K) patrat
b) a+b+c = 4K + 5K+ 3K = 12 K
12 K = 36
K = 3
a = 12 ; b = 15 ; c = 9
a = 4K
b = 5K
c = 3K
a patrat + c patrat = (4K) patrat + (3K) patrat = 16 K patrat + 9 K patrat = 25 K patrat = (5K) patrat
a patrat + c patrat = (5K) patrat
b) a+b+c = 4K + 5K+ 3K = 12 K
