Method: teorema de Pitágoras. Verified step-by-step solution with our free AI math solver.
Problem

a2+b2=c2, a=9, b=12a^2 + b^2 = c^2,\ a=9,\ b=12

Step-by-step solution

  1. Aplique a2+b2=c2a^2 + b^2 = c^2: 81+144=c281 + 144 = c^2, então c2=225c^2 = 225.

  2. Extraia a raiz quadrada positiva: c=15c = 15.

  3. (9,12,15)(9, 12, 15) é a terna (3,4,5)(3, 4, 5) multiplicada por 33.

Answer

c=15c = 15
