Step-by-step explanation:
I am not sure what you mean.
do you mean to see, if this can be a right-angled triangle, and if so, what is the Hypotenuse, and what are the legs ?
I assume this to be the case.
so, we must be able to build a Pythagoras equality
c² = a² + b²
28² = 784
53² = 2809
45² = 2025
indeed, we see right away, 45² + 28² = 53²
confirmed, it is a right-angled triangle, with 53 being the Hypotenuse.
