Answer:
a = 5 ; b = 12 ; c = 13
Step-by-step explanation:
a and b represent the legs of the triangle and c represents the hypotenuse, or longest side, of the triangle. Knowing this, we can substitute the values in to solve for the other leg.
a² + b² = c²
⇒ 5² + b² = 13²
⇒ 25 + b² = 169
⇒ b² = 144
⇒ b = 12
