Answer:
Yes, is a Pythagorean triple
Step-by-step explanation:
To know if you can build a right triangle with those sides we have to make the following equality
h² = l1² + l2²
The hypotenuse is always the longest side so it should be 73
we check the equality of the equation
73² = 48² + 55²
5329 = 2304 + 3024
5329 = 5329
Equality was fulfilled so it is a right triangle
